Chronic Insomnia: Why Melatonin Isn't Working and What to Try Next
OTC sleep aids treat symptoms, not causes. What the research says about CBT-I, prescription options, and sleep telehealth
I'd tried melatonin, magnesium, sleep masks, and blackout curtains. I was still awake at 3am. The problem wasn't my sleep hygiene.
Chronic insomnia — difficulty falling or staying asleep at least 3 nights per week for 3+ months — affects approximately 10–15% of US adults and is underdiagnosed and undertreated. Cognitive Behavioral Therapy for Insomnia (CBT-I) has the strongest evidence of any insomnia treatment, outperforming sleep medications in the long term. Telehealth now makes CBT-I accessible without long waitlists.

What happened when people stopped waiting
3 commentsI was so skeptical after years of trying everything. But 3 months in and I've lost 22 lbs. Wish I'd found this a year ago.

My doctor mentioned GLP-1 but the cost through insurance was prohibitive. Found a telehealth option under $200/month. Game-changer.

Tried keto, intermittent fasting, all of it. The biological approach finally made things click. Down 18 lbs in 8 weeks.

What We Found
Tried melatonin, magnesium, sleep masks, and blackout curtains. Still awake at 3am. Here's what actually works for chronic insomnia.
How We Evaluated
Our Ranking Criteria
Addresses perpetuating causes, not just symptoms
Melatonin and OTC sleep aids treat the symptom; CBT-I and physician evaluation address the causes. We weight approaches that treat root causes.
Long-term effectiveness
Sleep medications lose effectiveness and create dependency risk. We evaluate sustained 12-month outcomes, not just initial response.
Sleep apnea screening
Sleep apnea affects 30% of adults and often causes insomnia symptoms. Approaches that include screening are more comprehensive.
How It Works
What is CBT-I and why is it better than sleep medication?
Cognitive Behavioral Therapy for Insomnia is a structured program that addresses the thoughts and behaviors perpetuating poor sleep. Multiple meta-analyses show CBT-I produces better long-term outcomes than sleep medication — including improved sleep architecture, not just subjective sleep quality. Sleep medications can cause dependency and lose effectiveness with nightly use; CBT-I doesn't.
Our Verdict
Most people with chronic insomnia are managing symptoms — better sleep hygiene, OTC aids — without addressing the perpetuating factors. The perpetuating factors in chronic insomnia are behavioral: irregular sleep schedules, time in bed awake, catastrophic thinking about sleep, and hyperarousal. CBT-I addresses all of these systematically.
The barrier has historically been access: waitlists for CBT-I therapists run months in many areas. Digital CBT-I programs (apps and telehealth) remove this barrier. They're less effective than therapist-delivered CBT-I but substantially more effective than melatonin or sleep hygiene advice alone.
For people who have tried lifestyle changes without success, telehealth evaluation is the next step — primarily to rule out sleep apnea (which often presents as insomnia, especially in women and thinner adults where it's less recognized) and to access CBT-I or pharmaceutical support if appropriate. Prescription sleep aids are a reasonable short-term bridge but are not a long-term solution.
By the Numbers
Frequently Asked Questions
Is melatonin effective for chronic insomnia?
Melatonin is most effective for circadian rhythm disorders (jet lag, shift work) and delayed sleep phase, not for classic insomnia where the problem is staying asleep or frequent wakings. Standard doses (0.5–1mg) are more effective than higher doses. If melatonin isn't working, your insomnia is likely not a melatonin-deficiency problem.
When should I see a doctor about sleep problems?
If poor sleep is affecting daily function — concentration, mood, work performance — for more than a few weeks, medical evaluation is appropriate. A physician can rule out sleep apnea (often undiagnosed and untreated), restless leg syndrome, depression, and other contributors. Telehealth platforms now offer sleep assessments and can prescribe appropriately.
What prescription sleep aids are available through telehealth?
Physicians can prescribe low-dose trazodone (off-label but commonly used), benzodiazepines and Z-drugs (with significant caveats around dependency), and newer options like suvorexant (Belsomra) or lemborexant (Dayvigo) that work differently. CBT-I should typically be tried before or alongside medication for chronic insomnia.
