Why Is Sleep So Unrefreshing During Benzodiazepine Withdrawal, and What Improves Sleep Quality?

Why does sleep fall apart when the dose comes down?

Sleep is often the first thing a benzodiazepine taper disturbs, and it is one of the last things to settle. People describe lying awake for hours, waking again and again, dreaming more vividly than they have in years, and getting up as tired as when they lay down. All four complaints have the same cause.

Benzodiazepines work by boosting gamma-aminobutyric acid (GABA), the brain’s main calming chemical. The Ashton Manual, written by Professor C. Heather Ashton, explains in its first chapter that with regular use the receptors that carry this signal become less responsive. When the dose is reduced, the calming system runs short before the receptors can readjust. Sleep that is worse than it was before the medication was started is known as rebound insomnia.

A person who sleeps badly as the dose falls is often told that this proves the medication is still needed, or that it proves an addiction. It proves neither. Physical dependence is not addiction. In fact, it is the nervous system’s adaptation to a medication taken as prescribed, and broken sleep during a taper is that adaptation showing itself.

So, what kind of sleep was the medication providing, and what happens to it during a taper?

The sleep a benzodiazepine gives is not normal sleep.

In Chapter III of the Ashton Manual, Professor Ashton wrote that the sleep these medications produce, though it may seem refreshing at first, “is not a normal sleep.” Benzodiazepines suppress both dreaming sleep, known as rapid eye movement (REM) sleep, and deep sleep, known as slow wave sleep. The extra sleep time they provide is spent mainly in light sleep.

She called dreaming sleep and deep sleep the two most important stages of sleep. With regular use, tolerance brings both back toward their earlier levels, but the Manual notes that the initial deficit remains.

Think of a phone left all night on a weak charger. It was plugged in for eight hours, and in the morning the battery is barely a third full. The hours were there. The charge was not.

More hours in bed do not fix the problem. Deeper sleep does, and it returns on its own schedule.

Why are the dreams so vivid, and why is sleep so fragmented?

When the medication is withdrawn, dreaming sleep rebounds. The Manual describes a marked increase in REM sleep, which also becomes more intense, so dreams turn vivid, nightmares may occur, and a person wakes many times during the night. Professor Ashton called this a normal reaction and, though unpleasant, a sign that healing has begun.

She also gave a rough figure. When the missed dreaming sleep has been made up, usually after about four to six weeks, the nightmares become less frequent and gradually fade. That is her observation, not a promise.

Deep sleep takes longer to return, probably, she wrote, because anxiety is high, the brain is overactive, and it is hard to relax completely. The Manual lists trouble getting off to sleep, restless legs, sudden muscle jerks just as a person drops off, and being jolted awake by a loud bang that was never there. These disturbances may last for several weeks, sometimes months. Another article explains why insomnia gets worse during a benzodiazepine taper.

Why does a full night in bed still leave a person exhausted?

This is non-restorative sleep, and it is not the same thing as insomnia. The person does sleep, sometimes for seven or eight hours, and still wakes unrefreshed. Patients often describe heavy limbs, a short temper, poor concentration, and a need to lie down by early afternoon.

The likely explanation is the phone on the weak charger. While dreaming sleep rebounds and deep sleep lags behind, the hours in bed are light and broken, and they restore very little. A separate article covers benzo withdrawal fatigue and how a slower taper helps with it.

Then, the days and the nights begin to feed each other. A poor night raises the next day’s anxiety, and an anxious day makes the next night lighter.

Unrefreshing sleep is not proof that the medication was needed after all. It improves with a slow taper and with time, and a stronger pill does not hurry it.

Unfortunately, another sleeping pill is not a way out.

The obvious answer to bad sleep is a different sleeping pill, and it is the wrong one. Table 1 in the Manual’s first chapter lists zaleplon (Sonata), zolpidem (Ambien), zopiclone, and eszopiclone (Lunesta), often called z-drugs, as non-benzodiazepines with similar effects. Its footnote says they are chemically different from benzodiazepines but “have the same effects on the body and act by the same mechanisms.”

Chapter III says that most other sleeping pills and sedatives act in a similar way, and Professor Ashton included alcohol on that list. None of them, she wrote, should be used as alternative sleeping pills during benzodiazepine withdrawal. Earlier in the same chapter she wrote that drugs with benzodiazepine-like properties “only substitute one type of dependence for another.”

The Maudsley Deprescribing Guidelines add that sleep induced by z-drugs shows less slow wave sleep than normal sleep, and that their effect on sleep diminishes over time because of tolerance. So, the pill that promises a better night does not supply the deep sleep that is missing.

What about a medication from a different class? The Manual allows that, occasionally, another drug might be indicated. That question belongs with the person’s own prescriber, who can weigh the risks first.

Dr. Leeds is an osteopathic physician and deprescribing specialist in Fort Lauderdale, Florida. As a rule, he avoids adding a medication that may bring a physical dependence of its own.

Fortunately, the taper itself is the first sleep tool.

When sleep falls apart after a dose reduction, the first question is whether the taper has moved faster than the nervous system can follow. A short hold at the current dose is an ordinary part of a taper, and the next reduction can be smaller.

Chapter II of the Manual suggests reductions of up to one tenth of the dose at each step, with the patient in control of the pace. The Maudsley Deprescribing Guidelines describe hyperbolic tapering, in which the steps get smaller as the dose gets lower. If the nights keep getting worse, the doctor must advise slowing down.

Timing matters as well. Chapter II says that when insomnia is a major problem, most of the dosage can be taken at bedtime. Any change to when a dose is taken is worked out with the prescriber first, and another article explains why the evening dose matters most in a Valium taper.

With a short-acting benzodiazepine, waking in the small hours can be the medication wearing off before morning. A crossover taper to diazepam, described in the same chapter, keeps the level steadier through the night, and Dr. Leeds uses it where it helps.

What a hard night never calls for is stopping the medication. The United States Food and Drug Administration (FDA) warned in its 2020 boxed warning update that stopping a benzodiazepine abruptly, or reducing the dose too quickly, can cause withdrawal reactions, including seizures, that can be life-threatening. Call 911 for a seizure or any other medical emergency, and call or text 988, the Suicide and Crisis Lifeline, if exhaustion ever brings thoughts of self-harm.

What daily habits improve sleep quality during a taper?

The habit that matters most is a consistent routine. The same wake time every morning, weekends included, gives the body’s clock a fixed point. Sleeping late after a bad night feels earned. Yet, it usually pushes the next night later.

The Maudsley Deprescribing Guidelines fit the rest into one sentence: a stable sleep and wake schedule, light in the morning, less light at night, exercise, a relaxation routine, and limited naps and caffeine in the afternoon. The Ashton Manual adds avoiding tea, coffee, other stimulants, or alcohol near bedtime. A cool, dark, quiet bedroom and a phone left in another room belong with them.

Mornings matter as much as evenings, and another article covers daylight and sleep during a taper. A few lines written each morning, with the bedtime, the wake time, and any change in dose, show whether a bad week followed a reduction. That is what the prescriber needs to know.

None of these habits produces deep sleep on demand. They keep the body’s clock steady, and they are already in place when deep sleep returns.

Do structured sleep programs, melatonin, or herbal remedies help?

A structured sleep-behavior program is usually taught over several sessions by a trained therapist, and works on sleep without medication. It sets a regular sleep window, keeps the bed for sleep only, and teaches a person how to answer the thought at 3 in the morning that tomorrow is already ruined.

The Maudsley Deprescribing Guidelines state that this kind of program is more effective than hypnotics, meaning sleeping pills, for sleep. Yet, the same Guidelines note that adding such therapy to a taper did not improve longer-term results, perhaps because the withdrawal process has a large physiological component that can only be accommodated by gradual tapering.

So, it is a set of skills, and it does not replace a slower taper. A person who wants it can arrange it alongside the taper.

Melatonin, valerian, chamomile, lavender, and sedating antihistamines are a different matter. Evidence that any of them improves sleep during benzodiazepine withdrawal is limited, and individual response varies. Each one is a decision to make per patient, with a physician who understands the pharmacology, and none of them replaces a gradual taper.

Sleep does come back, but not on a schedule.

There is no fixed date. The Manual says it is impossible to give an exact time for the duration of withdrawal symptoms, and it adds that insomnia occasionally persists by itself for many months after other symptoms have gone. Sleep usually improves in stretches, with good nights and bad nights mixed, and the good stretches grow longer.

A person whose doctor once said that this medication was safe to take every night has good reason to doubt a doctor who now asks for patience. However, on this point Professor Ashton was direct. Poor sleepers, she wrote, “can be reassured that an adequate sleep pattern does return at last.”

Dr. Leeds’ practice focuses on medically supervised tapering of benzodiazepines and z-drugs for patients in Florida. It is a concierge practice with one physician, and the taper is gradual, patient directed, and measured in months, sometimes longer, with the quality of the nights helping to set the pace.
