Chronic insomnia treatment: causes, CBT-I and whether sleeping pills cause dependence

What is chronic insomnia, and where does treatment start?

Chronic insomnia treatment starts with two steps before any medicine: finding what stops you sleeping, then rebuilding your sleep habits with a short program called cognitive behavioral therapy for insomnia. The US National Heart, Lung, and Blood Institute (NHLBI) and Cleveland Clinic describe this program as the first treatment option for insomnia, while sleeping pills remain an option for the doctor alone to decide, usually for a short time. Your condition is treatable, not just "the way you are".

Chronic insomnia, as the NHLBI defines it, is difficulty falling asleep, staying asleep or getting good-quality sleep that happens 3 or more nights a week, lasts more than 3 months, and can't be fully explained by another health problem. A few bad nights from stress, travel or a schedule change is short-term insomnia, lasting days or weeks.

Insomnia is common: Cleveland Clinic (page updated 2026) says about 1 in 3 adults worldwide have symptoms of insomnia, and about 10% of adults have chronic insomnia. You are not a rare or strange case.

• Every night it takes you ages to fall asleep, though you are exhausted.
• You wake repeatedly in the night, or too early, and can't get back to sleep.
• You get up feeling you haven't rested at all.
• Your day suffers: tiredness, poor concentration and memory, irritability, or sleepiness that puts your driving and work at risk.
• You watch the clock counting the hours left, and dread the night before it comes.

Why can't I sleep at night? Causes to check before any treatment

Insomnia often has another cause behind it, and treating that cause is a core part of treating the insomnia.

Physical and medical causes

• Chronic pain or discomfort that wakes you at night, such as joint, muscle or nerve pain, including with arthritis and Parkinson's disease.
• Sleep apnea, with snoring and pauses in breathing during sleep, which your bed partner may notice first.
• Thyroid problems, acid reflux and allergies.
• Waking to urinate at night because of an enlarged prostate or another medical problem.
• Pregnancy, hormonal changes in women, and menopause.
• Medicines taken for something else, such as some cold medicines and weight-loss pills. Don't stop them yourself; tell your doctor.

Habits and substances that steal your sleep

• Caffeine in coffee, tea and energy drinks, especially late in the day.
• Nicotine in cigarettes, shisha and e-cigarettes, especially close to bedtime, as it can make it harder to fall asleep.
• Alcohol: it may help you drift off early in the night, then makes your sleep broken and poor later on.
• Drugs such as cocaine and ecstasy.
• Irregular sleep times, long daytime naps and too little activity.
• Night-shift work and travel across time zones.
• Screens right before bed, light, noise, a room too hot or cold, or an uncomfortable bed.
• Daily stress and worries, clock-watching and anxiety about not sleeping, which on its own can be enough to keep you awake.

Often the last obstacle is the mind: the light goes out and the whole day starts replaying. If that is you, also read overthinking before sleep and how to stop it.

Insomnia, anxiety and depression: which causes which?

It runs both ways: anxiety, depression and bipolar disorder are known causes of insomnia, and Cleveland Clinic notes that lack of sleep can raise the risk of depression and anxiety, and that about half of people with chronic insomnia also have at least one mental health condition, such as anxiety or depression.

So ask not only "how do I sleep?" but "what keeps me on edge?" Signs worth noticing:

• Loss of pleasure and interest in things you used to enjoy, and sadness or emptiness most of the day, most days.
• Constant worry and physical tension: palpitations, tight muscles, an upset stomach, a sense of looming disaster.
• Crying for no clear reason, or feeling like a burden to those around you.
• Insomnia that doesn't improve however much you adjust your habits and schedule.

Look at the signs of depression and how it differs from ordinary sadness, and if many apply, ask for a psychiatric assessment. The good news is that both can be treated in one plan: MedlinePlus explains that some medicines for anxiety and depression also help with sleep, and that CBT for insomnia may help you control anxiety or depression and your sleep at the same time.

Insomnia and withdrawal: when sleep is the victim of a substance or medicine

Some people start alcohol or a sedative "just to sleep", but this fix works against itself: a 2014 review in the Handbook of Clinical Neurology shows that alcohol before bed shortens the time to fall asleep and changes sleep structure in the first part of the night, then sleep becomes broken and poor in the second part. The review also notes that the body builds tolerance to alcohol with repeated use, although few studies have tracked its effects on sleep night after night.

Insomnia is also a symptom of withdrawal. The same review notes that sleep problems in people with alcohol dependence can persist for months after stopping and may play a part in relapse. The US Food and Drug Administration (2020) lists insomnia among the symptoms of benzodiazepine withdrawal, and notes that some protracted withdrawal symptoms can last from weeks to 12 months. So stopping should be medically planned, with a plan for sleep itself, not a sudden midnight decision.

CBT for insomnia (CBT-I): the first choice, step by step

The NHLBI describes cognitive behavioral therapy for insomnia as a treatment plan lasting 6 to 8 weeks, usually recommended as the first option for long-term insomnia, and one that can be very effective. A doctor, nurse or therapist delivers it in person, by phone or online, and the NHS notes it can also be a self-help online program.

Its connected parts, which the therapist works on with you:

• Sleep education: understanding how sleep works, and which habits help it and which ruin it.
• Stimulus control: regular sleep and wake times, and linking bed with sleep rather than wakefulness and worry: go to bed only when sleepy, get up if you can't sleep, and keep the bed for sleep, not your phone or work.
• Managing time in bed (sleep restriction): the therapist sets a specific time in bed with you and adjusts it as you progress. It is done with a professional and follow-up, not by guesswork.
• Relaxation or meditation: you learn ways to calm your body and mind that help you fall asleep faster.
• Cognitive therapy: eases stress about not sleeping, working on thoughts like "I won't sleep tonight" and "tomorrow will fall apart", turning them into more realistic, less alarming ones.

Sleep habits experts recommend, starting tonight

The NHS says insomnia usually improves by changing sleep habits; these are its recommendations. Even if they aren't enough alone, they stay part of any treatment plan.

• Only go to bed when you feel sleepy.
• Wake up and get out of bed at the same time every day.
• Relax for at least an hour before bed, for example with a warm bath or a book.
• Make your room dark and quiet, with curtains, an eye mask or earplugs if needed, and make your mattress, pillows and covers comfortable.
• Exercise regularly during the day.

On the other hand, things to avoid:

• No smoking, alcohol, tea or coffee for at least the last six hours before bed.
• No big meal late at night.
• No exercise in the last four hours before bed.
• No TV or phone right before bed, because the blue light makes you more awake.
• No daytime naps.
• Don't lie in after a bad night; stick to your usual times.
• Don't drive when you feel sleepy.

Are sleeping pills addictive? And what is the safe rule?

Short answer: yes, some can cause tolerance and dependence. The NHS says GPs now rarely prescribe sleeping pills for insomnia, because they can have serious side effects and people can become dependent on them, and that they are only prescribed for a few days or weeks at most, if insomnia is very bad or other treatments haven't worked.

MedlinePlus explains that most over-the-counter sleeping pills contain antihistamines and the body gets used to them quickly, and that most prescription sleep medicines can be habit forming and work less well over time. In time you may take them from fear of a sleepless night rather than to sleep better: an exhausting cycle.

In September 2020 the US Food and Drug Administration required an update to the Boxed Warning on all benzodiazepines (a class used for anxiety, insomnia and seizures) to cover the risks of abuse, addiction, physical dependence and withdrawal reactions. It states that physical dependence can develop with steady use for several days to weeks, even as prescribed, and asks doctors to keep the amount and duration to the minimum needed.

If you can no longer sleep without them, have increased the amount yourself, or fear running out and seek them in several places, these are signs of sleeping-pill dependence to discuss with a psychiatrist without embarrassment. Dependence is not a moral failing or weak will, but a treatable medical condition.

There are other classes of medicine a doctor may use in certain cases, including ones that act on melatonin receptors and orexin receptor antagonists, and their availability may differ from country to country; the NHLBI notes that some prescription insomnia medicines are meant for short-term use and others for longer-term use. Choosing a medicine, its duration and fit with your other medicines is purely a medical decision; never take one prescribed for someone else, however similar their situation seems.

When should you get medical help for insomnia?

The NHS advises seeing a doctor if changing your habits hasn't worked, if insomnia has lasted months, or if it affects your daily life in a way that makes it hard to cope. These signs should not be put off:

• It has started to affect your work, study, driving or relationships with your family.
• You sleep enough hours but always wake up exhausted, or people around you say you snore loudly and stop breathing for moments.
• It comes with persistent sadness, severe anxiety or night-time panic attacks.
• You have started drinking alcohol or using something in order to sleep.
• You have increased your sleep medicine on your own, or tried to stop and couldn't, or developed distressing symptoms.

How does treatment work at Oxygen Center?

It begins with a calm psychiatric assessment: your sleep story, what you have tried, your current medicines, and whether depression, anxiety or a physical problem needing referral lies behind the insomnia. You may be asked to record your sleep and wake times in a sleep diary for a week before the plan is drawn up.

• Follow-up appointments with a psychiatrist to diagnose what lies behind the insomnia and adjust any medicine, including a gradual tapering plan if you depend on a sleeping pill.
• Psychotherapy sessions in which the therapist works through the CBT for insomnia program with you step by step.
• Short regular follow-ups to review your sleep diary and adjust the plan, since sleep improves gradually.
