Tolerance Withdrawal

Tolerance Withdrawal

The first signs of the coming storm

By David Powers, Ph.D.

Tolerance is a term often used to describe how our brain can sometimes adapt to a drug’s effect, so that the same dose feels weaker over time. With benzodiazepines, that adaptation lives mainly in GABA-A receptor systems and the networks they modulate (stress circuits, sleep circuits, learning/memory). When the effect shrinks but the dose hasn’t changed, people often say they feel “in withdrawal on a stable dose.” That sensation is what the community calls “tolerance withdrawal.”

Tolerance is another one of those buzzwords in the benzo community that is often misused or used interchangeably with other terms, such as BIND or acute withdrawal. Many people will make the claim that their benzo "suddenly stopped working", which, of course, isn't quite accurate, or else they'd likely experience seizures.

It's not that the benzo suddenly entirely stopped working, but that their system has adapted, and the drug is no longer producing the same effects. However, there are other factors to consider that might also better explain what's happening. Let's explore tolerance with some clarity and dispel any confusion and fear.

The Coffee Effect

Let's use a metaphor to simplify things. Think of tolerance like the first time you ever drank coffee. Initially, one cup might have made you feel wired. But after drinking it daily for a while, that same cup barely registers, not because the coffee disappeared, but because your body adjusted. Benzos work the same way. The brain adapts to its calming signal, so the same dose feels weaker over time.

This is when many people feel the need to increase their dose. This happened to your Coach. Initially, 2mg of Valium worked amazingly, but over time, I needed more and more to get the same effect. Eventually, I was up to 40mg Valium and still not really feeling it. Sort of like someone who builds tolerance to coffee and can drink 3-4 cups a day and barely feels a difference.

At that point, for both the benzo user and coffee drinker, they use the drug just to feel normal and avoid withdrawal or feeling less normal without the drug.

The Difference Between Benzos & Coffee

While in simple terms we can understand tolerance by comparing benzos to coffee, there is an important distinction worth noting. With coffee, once your body has adapted, switching to another brand or roast doesn’t really “reset” things. Your tolerance goes with you, assuming you're still consuming the same milligrams of caffeine.

Benzos are a little different. Because each benzo has a slightly different chemical profile (different half-lives, different receptor-binding characteristics), people sometimes feel a “reset” when they switch medications. For example, someone may build tolerance to Ativan but feel more effect when they cross over to Valium or Klonopin, at least for a while.

But here’s the key: this isn’t a true reset of tolerance. It’s more like shifting which doorways the benzo is using in the brain. You may get temporary relief, but the nervous system still adapts over time. That’s why rotating benzos is not a cure, and why tapering remains the long-term solution for many people.

So while the coffee metaphor helps us see how tolerance builds, the benzo difference reminds us that there can be short-term relief with a switch, but the underlying adaptation is still there. But this gets even more nuanced, as we will explore more in this lesson.

When Tolerance Seems to Reverse

Usually, tolerance means the brain has adapted to the drug, and it won’t suddenly “reset” unless you change the dose or the drug. However, that's not always true. As a recovery coach, I can tell you that I've seen countless people enter tolerance, and then with time and work, feel as though the tolerance seemed to reverse itself, and they became stabilized again.

Here’s why someone can sometimes feel like the benzo starts working better after a long hold, a decrease in stress in their lives, or after self-work:

1. Fear vs. Function: When the Bear (fear circuitry) is in overdrive, it can override the calming effect of the benzo. You’re taking the pill, but you’re also feeding panic, hypervigilance, and constant “what ifs.” That storm of cortisol and adrenaline can make it feel like the benzo does “nothing.” I often use the analogy of benzos being like a glass of water. The water must be proportionate to the fire it's intended to put out. If that fire grows larger (i.e., increase in life stressors, sickness, grief, burnout, depression, etc.), then it will require more water.

2. Neuroplastic Catch-Up: If someone holds their dose for a long stretch and works on fear retraining, mindfulness, or healthy routines, the nervous system begins to calm and rebalance. A recalibration can occur even while still on the benzo. Once the background stress tone drops, the medication’s effect can “show through” more clearly again.

3. Stress vs. Dose Confusion: Sometimes people mistake life stress or a bad wave for “tolerance.” But when the stress calms down, the benzo feels effective again, even though nothing about the dose changed. This can be related to fear, as well as to stress in general, as mentioned above. Everyday stressors like job burnout, financial stress, family difficulties, death, divorce, sickness, and even existential crisis can considerably raise glutamate, cortisol, histamine, and norepinephrine, making the benzo feel less powerful, or as if you're in tolerance.

So it’s less that tolerance magically reversed, and more that the brain stopped drowning out the medication’s effect with hyperarousal.

What Actually Changes in the Brain with Tolerance?

When we talk about tolerance, it’s not that your brain “runs out of GABA.” The issue is how the brain’s receptors respond to it.

1. Receptors adjust their sensitivity.

Think of GABA-A receptors like door locks, and benzos/GABA are the keys. Over time, the locks become harder to turn. They don’t open as easily. Scientists call this “desensitization” or “uncoupling.” The key is still there, but the lock doesn’t respond the same way.

2. The other side of the seesaw pushes back.

If the calming side (GABA) is boosted for weeks or months, the brain’s excitatory systems (like glutamate and stress hormones) nudge upward to keep balance. It’s like turning down the volume on a loud TV. The rest of the house gets quieter to compensate, until the TV feels “normal” again.

3. It’s network-wide, not just one switch.

These changes ripple through whole systems: sleep cycles, attention, threat detection, and even body awareness. That’s why tolerance doesn’t just feel like “less anxiety relief," but also like poor sleep, brain fog, or heightened physical symptoms. This can further create dysregulation and powerfully awaken the Bear, which can then begin to form conditioned fear responses, or "loop/reflexes," around the symptoms of dysregulation.

Key takeaway: Tolerance is about functional adaptation, not permanent damage. The very plasticity that created these changes is the same force we rely on for recovery. With time, tapering, and retraining, the brain can reset those locks and rebalance the seesaw.

How Fast Does Tolerance Happen?

Tolerance doesn’t arrive all at once, like flipping a switch. It’s more like different lights dimming at different speeds in different rooms:

Sleepiness light: This one often dims the fastest, within days or weeks, the “knock-out” effect fades.

Anxiety relief light: This dimmer is slower and less predictable. Some people still notice calm for months, others feel it fade more quickly.

Seizure protection light: In medical use for epilepsy, doctors know tolerance builds here too, which is why benzos aren’t a long-term fix for seizures.

What makes lights dim faster? Higher doses, short-acting benzos (like Xanax or Ativan), irregular use, high stress, and personal biology.

Bottom line for students: Tolerance isn’t “everything gone in a few days.” Some effects fade fast, some linger, and the timeline is different for everyone.

Why do some people never seem to build tolerance?

To make things more confusing, it’s true that many people can take the same dose of a benzo for sleep or anxiety for years and never feel like they need more. Indeed, I've seen countless people who took the same dose for 20 or more years with no reported tolerance or issues.

But how can that be, when we just said tolerance is real?

Different Brain Wiring

Not all nervous systems respond to benzos in the same way. Genetics and individual brain chemistry set the “pace” for tolerance and recovery.

Receptor sensitivity: Some people are naturally more sensitive to GABA and glutamate shifts. Their receptors adjust quickly, so tolerance shows up faster. Others adapt more slowly, so the same dose keeps working longer.

Metabolism & enzymes: The liver’s cytochrome enzymes (like CYP3A4) break down benzos. Variations in these genes mean some people clear benzos faster (shorter effect, higher tolerance risk) while others hold onto them longer (slower tolerance buildup).

Baseline wiring: If someone already has a highly reactive limbic system (anxious temperament, HSP, history of trauma), tolerance can feel harsher because the Bear is already on high alert. Someone with a steadier baseline may not notice the same shifts.

Other meds & health: Antidepressants, hormones, sleep meds, even diet and gut health can tilt the balance of how the nervous system adapts.

Key takeaway: Tolerance is common, but not universal. It depends on dose, drug, biology, and life context. What matters most in recovery isn’t comparing yourself to “the person who took 0.25 Xanax for 20 years,” but understanding your own nervous system and how to help it recalibrate.

Context Matters

Tolerance doesn’t build in a vacuum. The stress level of your life, your environment, your mindset, and even your daily habits all change how fast the drug feels like it “stops working.”

Chronic stress & fear: If the Bear is roaring all day long, producing constant worry, high pressure, trauma reminders, your body is already flooded with cortisol and adrenaline. That stress load can drown out the calming effect of the benzo, making it feel like tolerance is racing ahead.

Calm environments: On the flip side, someone in a supportive, steady environment may find that a small dose continues to “work” for years, because the benzo isn’t fighting against a wall of chronic hyperarousal.

Lifestyle factors: Poor sleep, chaotic schedules, or toxic relationships can magnify the sense of tolerance. Conversely, routines that reduce baseline stress (exercise, healthy boundaries, safe community) can make a dose feel more stable.

Low, Steady Doses

Not all benzo use creates tolerance in the same way. How much you take, and how often, changes the picture.

Small vs. large doses: A tiny bedtime dose of Xanax (say, 0.25 mg) is very different from taking several milligrams across the day. The smaller the dose, the less overall disruption to the GABA system, which slows down tolerance.

Once-a-day vs. multiple times: Taking a benzo once daily for sleep gives the nervous system long stretches to stabilize between doses. In contrast, taking it three or four times daily keeps the system constantly bathed in the drug, which accelerates adaptation.

Stability vs. yo-yoing: Keeping the dose consistent over time can create a fragile kind of “equilibrium.” But yo-yo dosing, taking more on bad days, less on good days, teaches the brain to chase balance, and tolerance tends to show up faster.

Perception vs. Biology

Sometimes tolerance is happening under the surface, but the person doesn’t really notice it because their main goal is still being met.

Specific goals: If the purpose of a small nightly dose is just to help someone fall asleep, even a little effect may feel “good enough.” They may not care (or even realize) that the overall sedation is less than it was at first.

Relative improvement: If symptoms aren’t gone but are noticeably better than without the benzo, the brain often interprets that as “it’s still working.”

Shifting baselines: People naturally adapt to what “normal” feels like. If tolerance creeps in gradually, the person may not register the change, because the dose still seems to “do something.”

Key takeaway: Tolerance isn’t always obvious. Sometimes the biology has shifted, but if the benzo still meets the person’s specific need, their perception is that it’s effective.

Tolerance or Something Else?

Many students come into recovery believing they’ve developed “tolerance”, that their medication has suddenly stopped working because their brain has permanently adapted. And yes, true tolerance does exist. Over time, the nervous system can adjust to benzodiazepines, making the same dose feel less effective. This is what we mean by pharmacological tolerance, and it can happen even in the absence of any new life stress.

But often, when I hear students tell their stories, something else emerges. They describe a season of life filled with heavy stressors, sickness, grief, burnout, the loss of a job or relationship, or the accumulation of daily pressures that slowly wore them down. In those cases, it’s not always the brain “adapting” to the drug. Instead, it’s that the stress load has grown beyond what the medication can reasonably handle.

Think of it like this: benzodiazepines are a glass of water meant to put out a fire. For years, maybe that fire was just the size of a matchbox, and the water worked perfectly. But if that fire grows into a dumpster fire, if life’s stressors suddenly multiply, it’s not that the water stopped working, it’s that the fire became too big for the same glass of water. This is what I call apparent tolerance, or "situational intolerance."

The good news is that when we work to bring down stress, calm the Bear, and make healthy changes, this “tolerance” feeling often fades. In many cases, it disappears altogether. What felt like a failing drug turns out to be a mismatch between resources and stress load, not a permanent neurological change.

“Tolerance withdrawal” vs. other look-alikes

Students need this differentiation, or everything scary feels like “tolerance.”

1. Interdose withdrawal (short-acting meds, long gaps)

Pattern: Symptoms crest before the next dose and ease afterward.
Fix: Even out the curve (spacing, split dosing, switch to longer half-life, or a gradual taper plan).
Not the same as receptor tolerance; it’s mini-withdrawals between doses.

2. Baseline/anxiety return or new conditioned fear

The Bear (limbic alarm) can re-pair ordinary sensations with danger. That can look like “my benzo stopped working,” when it’s really fear loops + stress load.

3. Paradoxical effects / adverse effects

Irritability, agitation, insomnia, or depression can be drug side effects, not proof of tolerance.

4. Life factors that amplify symptoms

Sleep loss, caffeine, illness, perimenopause, thyroid shifts, grief, and doom-scrolling all matter greatly. Context can masquerade as tolerance.

Signs that true tolerance is likely

Same dose, steadily shrinking effect across weeks–months (after ruling out timing gaps and life stress spikes). Observable before reducing the benzo or discontinuation.

Dose increases help briefly, then fade, not associated with life stressors.

Functional domains track the effect (e.g., sedation tolerance shows up as alertness returning at prior “sleepy” doses). Benzos are less effective for sleep. However, this can also be significantly related to fear conditioning of insomnia (aka the Bear overriding the benzo).

Interdose pattern isn’t the driver (symptoms aren’t predominantly timing-linked).

Recovery work can still have a positive impact on true tolerance!

Not related to tapering & withdrawal, which will produce a very similar effect.

Common myths (and cleaner truths)

Myth: “Tolerance means permanent brain damage.”

Truth: Tolerance reflects adaptive plasticity. Those adaptations are reversible with time off the drug and with fear-circuit retraining and healthier inputs. Benzos do not cause permanent brain changes or injuries, and they certainly do not cause brain damage.

Myth: “Everyone becomes fully tolerant to anxiolysis in weeks or months.”

Truth: Tolerance is highly variable. Sedation/sleep effects can wane fairly quickly for some, while anxiolysis can persist for others over many years. Tolerance within weeks is extremely rare. True tolerance tends to build gradually over years of use, often with lower-half-life benzos, inconsistent dosing, and other factors.

Myth: “If I feel bad on a stable dose, I must up-dose.”

Truth: Sometimes, smoothing dosing or beginning a thoughtful taper (while doing lulling/pushing work) reduces the yo-yo more than chasing the dose upward. Sometimes, up-dosing is helpful. Other times, it leads us to chase the Bear.

Myth: “Two benzos solve tolerance.”

Truth: Stacking typically complicates adaptation and taper later. However, it is common practice for doctors to prescribe two benzos. I.e, valium (longer half-life) for daily use, and xanax (shortest half-life) for sleep or "break-through" anxiety attacks. I.e., to ward off a panic attack, flying anxiety, etc.

Last word: Try your best not to confuse tolerance for other things, or allow the Bear to run wild with its catastrophic thinking and responses. The fear that the benzo will suddenly stop working is among the most widespread in the benzo community. However, the benzo doesn't merely "stop" working, as I hope you now understand by reading this lesson.

And if you're tapering your benzo, then you're not in "tolerance", you're experiencing withdrawal. We cannot reduce the drug dose and expect it to have the same effects as our usual dose, which may not have been those effects in the first place.

Regardless of withdrawal, acute, interdose, or tolerance, with steady, intelligent neuroplasticity work, leadership building, daily consistent rhythms, and mastering the art of lulling and pushing, you may be pleasantly surprised at how positively impactful these things can be in your recovery!
