Insomnia treatment (CBT-I)

The treatment for chronic insomnia that isn't medication.

Cognitive Behavioral Therapy for Insomnia — CBT-I — is the first-line, evidence-based treatment for chronic insomnia recommended by the American College of Physicians, the American Academy of Sleep Medicine, and major menopause societies. It works for the majority of patients who complete the course. Most clinicians don't offer it. Dr. Shelby Harris has been delivering it in private practice for over two decades.

Why you're stuck

Sleep is the one biological system that collapses under demand.

Most patients arrive after years of trying harder.

More rituals. More trackers. More supplements. More math at 2 a.m. about how many hours they'll get if they fall asleep right now. None of it works, and many of them have figured out that the trying is part of the problem — they just don't know what to do instead.

This is the paradox: the harder you try to sleep, the less you sleep. Sleep doesn't respond to effort the way other systems do. You can will yourself through a workout. You can power through a hard week at work. You cannot will yourself to sleep. The pressure makes the system collapse faster.

Chronic insomnia isn't a willpower problem. It isn't a hygiene problem. It's a learned pattern — your body and brain have developed a conditioned arousal response to the bed itself — and it needs a structured clinical intervention to unlearn it.

That intervention is CBT-I.

The treatment

Generally a 6 to 8 session course, tailored to the patient’s needs. Not therapy in the open-ended sense.

I use an evidence-based CBT-I framework, while tailoring treatment to each patient’s needs, goals, and readiness for change. I personalize the process to fit the patient rather than forcing the patient to fit a rigid protocol. The full course of therapy is generally 6 to 8 sessions, depending on medical and psychiatric complexity and if medications are being tapered. Patients typically see meaningful improvement by the 4th or 5th session.

Rather than relying on quick fixes

CBT-I targets the behavioral and cognitive patterns that sustain poor sleep. This includes carefully adjusting time in bed to rebuild sleep efficiency, strengthening the bed–sleep connection through stimulus control strategies, and working directly with the thoughts that keep the brain activated at night so they become more accurate and less disruptive. Foundational sleep habits are also addressed, but as a support—not the core treatment.

The goal is to help you consolidate sleep, reduce nighttime wakefulness, and restore a more reliable, predictable sleep pattern over time.

A common misunderstanding

Sleep hygiene is important. It isn't the treatment.

Sleep hygiene is important the way dental hygiene is important. You brush your teeth twice a day, you floss, you avoid sugar — and that's the right baseline. But once you have a cavity, brushing harder doesn't fix it. You need a dentist to actually treat the cavity.

Chronic insomnia is the cavity. Sleep hygiene is the brushing.

By the time most patients reach a behavioral sleep specialist, they've been doing all the right hygiene practices for months or years — and the insomnia is still there. That isn't a failure of effort. It's a misdiagnosis of the problem. The conditioned arousal pattern in the brain doesn't respond to hygiene. It responds to the structured behavioral intervention that CBT-I provides.

Did you know

What patients usually believe before they start.
Misconception If sleep is making my anxiety worse, shouldn’t I just try harder to sleep?
what's actually true

Trying harder to sleep when you’re anxious is the textbook driver of insomnia. The effort itself increases arousal. CBT-I removes the effort from the system — which sounds counterintuitive until you’ve experienced how much of the problem is the trying.

Misconception Don’t I have to treat my anxiety before I can address my sleep?
what's actually true

CBT-I targets the sleep mechanism directly. Treating the sleep often reduces anxiety as a result. The two conditions don’t need to be addressed sequentially — and many patients find that resolving the sleep improves the anxiety more than they expected.

Misconception If I haven’t slept well, shouldn’t I go to bed earlier the next night?
what's actually true

Going to bed earlier after a bad night reinforces the insomnia pattern. Instead, behavioral sleep medicine suggests to do opposite — maintain a consistent sleep/wake time regardless of how the night went, and let sleep pressure rebuild naturally.

Misconception Isn’t sleep restriction dangerous since I already can’t sleep?
what's actually true

Sleep restriction is counterintuitive but central to how CBT-I works. By consolidating time in bed, the sleep that does happen becomes deeper and more efficient. The restriction is temporary; the window expands as sleep improves. It can be modified to meet the patient where they are to encourage consistency.

Misconception Won’t CBT-I take years like other therapy?
what's actually true

Most patients complete CBT-I in six to eight sessions over twelve to sixteen weeks. The treatment is designed to end. The goal is to make the practice unnecessary.

Misconception Do I need to keep using my sleep tracker to make sure the treatment is working?
what's actually true

Sleep trackers tend to make insomnia worse. The sleep diary used in CBT-I is structured deliberately to track what matters without creating performance pressure.

Misconception Isn’t CBT-I just sleep hygiene with extra steps?
what's actually true

CBT-I and sleep hygiene are different interventions. Sleep hygiene addresses the environment and habits around sleep. CBT-I addresses the conditioned arousal pattern that makes the bed itself a place of wakefulness. Sleep hygiene is a small part in CBT-I, but for most people it isn’t the active ingredient.

Misconception Do I need a sleep study before I can start treatment?
what's actually true

Sleep studies diagnose conditions like sleep apnea, excessive sleepiness or parasomnias, not typically insomnia. CBT-I is the treatment gold standard treatment for insomnia — the diagnosis is clinical. A study may be appropriate if other sleep disorders are suspected or you’ve not responded to traditional treatment.

Misconception My insomnia is caused by anxiety, don’t I need to treat the anxiety first?
what's actually true

Anxiety and insomnia feed each other, but CBT-I targets the sleep mechanism directly. Treating sleep often reduces anxiety as a result.

Misconception I’ve had insomnia for fifteen years. Isn’t it too late for this kind of treatment?
what's actually true

Duration of insomnia is not a strong predictor of treatment success. Many patients have had chronic insomnia for decades and respond to treatment within six to eight weeks.

Misconception Don’t I have to be off medication before I start CBT-I?
what's actually true

Not true. Many patients begin CBT-I while still on a sleep medication. The treatment works alongside medication, and the medication taper — if appropriate — typically happens later, in coordination with the prescribing clinician.

Misconception If you can’t sleep, should I try harder?
what's actually true

Sleep is the one biological system that collapses under demand. The harder you try, the less you sleep. The treatment removes the effort, not adds to it.

Misconception Does sleep hygiene fix chronic insomnia?
what's actually true

Sleep hygiene is important — like dental hygiene is important. But once you have a cavity, hygiene doesn’t fix it. Chronic insomnia is the cavity.

Misconception Are the only options for insomnia years of suffering or years of medication?
what's actually true

There’s a third option. It’s called CBT-I, and it’s the recommended first-line treatment. Most people have never heard of it.
