About 4 in 10 Canadians report at least one insomnia symptom, and roughly 1 in 8 meet the criteria for insomnia as a disorder. The first-line treatment recommended by major medical guidelines is not a pill: it is cognitive behavioural therapy for insomnia (CBT-I), which works as well as sleeping pills in the short term and better in the long term.
Melatonin helps a little for most people and a lot for body-clock problems like jet lag. Prescription sleep drugs work but come with trade-offs. DSIP, the “delta sleep-inducing peptide,” has an intriguing name and a thin, inconsistent evidence base. Here is everything ranked.
What counts as insomnia
Everyone has bad nights. Chronic insomnia means trouble falling asleep, staying asleep or waking too early at least three nights a week for three months or more, despite having the chance to sleep, with daytime effects like fatigue, poor concentration or irritability.
A Canadian survey found 40% of adults reported at least one insomnia symptom and 13% met the criteria for insomnia syndrome (Morin et al., 2011). It is more common in women, older adults, shift workers and people with anxiety, depression or chronic pain.
Rule these out first
- Sleep apnea: loud snoring, gasping, morning headaches, daytime sleepiness. Very common and very treatable.
- Restless legs: an urge to move the legs in the evening, often linked to low iron.
- Mood disorders: depression and anxiety both disrupt sleep, and insomnia worsens both.
- Medications and substances: caffeine, alcohol, nicotine, some antidepressants, decongestants and steroids.
- Body-clock problems: shift work or a naturally late body clock (“night owl” delayed sleep phase).
- Menopause, thyroid problems, chronic pain and reflux.

CBT-I: the first-line treatment
The American College of Physicians recommends CBT-I as the initial treatment for all adults with chronic insomnia, ahead of medication (Qaseem et al., 2016). It is a structured program, usually 4 to 8 sessions, built on a few techniques:
- Sleep restriction: temporarily limiting time in bed to the time you actually sleep, which builds sleep pressure and consolidates sleep. Counterintuitive, and the most powerful part.
- Stimulus control: bed is for sleep only; if you are awake and frustrated, get up and return when sleepy. This retrains the brain to link bed with sleep.
- Cognitive work: tackling the anxious thoughts about sleep that keep you awake (“if I don’t sleep, tomorrow is ruined”).
- Consistent wake time, every day, including weekends.
The first two weeks can feel worse because of sleep restriction. Most people see clear improvement by week four to six, and unlike pills, the gains persist after treatment ends. Digital CBT-I programs and apps make it accessible without a waitlist.
Melatonin
Melatonin is the hormone your brain releases in darkness to signal night. In Canada it is sold over the counter as a natural health product. A meta-analysis found it shortened the time to fall asleep by about 7 minutes and increased total sleep by about 8 minutes on average: real, but modest (Ferracioli-Oda et al., 2013).
Where melatonin shines is timing problems: jet lag, shift work and a delayed body clock. For those, low amounts taken a few hours before the desired bedtime act as a clock signal rather than a sedative. It is generally well tolerated; grogginess and vivid dreams are the most common complaints.
Prescription sleep medications in Canada
- Zopiclone is the most prescribed sleeping pill in Canada. It works quickly, but tolerance can develop, and it carries risks of next-day impairment, falls in older adults and dependence. Generally intended for short-term use.
- Benzodiazepines (such as lorazepam) are effective sedatives but carry higher dependence risk and are discouraged for long-term insomnia.
- Orexin receptor antagonists such as lemborexant (Dayvigo) are a newer class. Rather than sedating the whole brain, they block orexin, a wake-promoting signal. They have less dependence potential than older drugs.
- Low-dose doxepin helps mainly with staying asleep.
- Trazodone, an older antidepressant, is widely prescribed off-label for sleep, though evidence specifically for insomnia is limited.
Sedative sleeping pills raise the risk of falls, hip fractures, confusion and car accidents in people over 65. Canadian deprescribing initiatives encourage CBT-I and gradual tapering instead. Never stop a long-term sleeping pill abruptly; taper with your prescriber.
Over-the-counter sleep aids
Most OTC “night-time” products contain sedating antihistamines like diphenhydramine. They cause drowsiness, but tolerance builds within days, they cause next-day grogginess, and their anticholinergic effects are a concern in older adults. Not a long-term solution.
Magnesium, CBD and other supplements
- Magnesium: may help people who are deficient; evidence in the general population is weak.
- CBD and cannabis: legal in Canada; evidence for insomnia is limited and mixed, and THC can worsen sleep quality over time.
- Valerian, chamomile, L-theanine, glycine: small or inconsistent effects. Low risk, low reward.
DSIP: what the sleep peptide research shows
Delta sleep-inducing peptide (DSIP) is a nine-amino-acid peptide first isolated in 1977 from the blood of rabbits put into deep sleep by electrical brain stimulation. When given to other animals, it appeared to increase deep, slow-wave (“delta”) sleep, hence the name.
Since then, the story has been less tidy:
- Small human studies in the 1980s reported improved sleep in some people with insomnia and in withdrawal from alcohol and opioids, but other studies found little effect.
- No specific DSIP receptor or gene has been identified, and its natural role is still debated.
- It is not approved as a medicine anywhere, and there are no modern controlled trials.
DSIP remains a research peptide with an interesting history and an unresolved mechanism. Our full write-up is in the DSIP peptide guide. TrueLabs supplies DSIP (from $35) as a research compound, with related research on the pineal-axis peptides Epithalon and Pinealon. These are for laboratory research only, not sleep aids.
Habits that actually matter
“Sleep hygiene” on its own rarely cures chronic insomnia, but a few habits make every other treatment work better:
- Fixed wake time, seven days a week.
- Morning daylight, especially through Canadian winters; it anchors your body clock.
- Caffeine cut-off by early afternoon (it has a half-life of about five hours).
- Alcohol: it helps you fall asleep but fragments the second half of the night.
- A cool, dark room and a wind-down buffer before bed.
- No clock-watching: turn the clock away.
Getting help in Canada
- Family doctor or nurse practitioner: covered by provincial health insurance; can screen for sleep apnea and other causes.
- Sleep studies: covered when ordered, though waits vary; home sleep apnea tests are increasingly common.
- CBT-I: delivered by psychologists (usually private or via extended health benefits), some sleep clinics, and digital programs, several of which are low-cost or free in some provinces.
FAQ
Tap a question to reveal the answer.
What is the best treatment for insomnia?
Cognitive behavioural therapy for insomnia (CBT-I) is the recommended first-line treatment. It works as well as medication in the short term and its benefits last after treatment ends.
Does melatonin work for insomnia?
Modestly. On average it helps people fall asleep about 7 minutes faster. It works much better for timing problems like jet lag or a late body clock.
Is melatonin legal in Canada?
Yes. Melatonin is sold over the counter in Canada as an authorized natural health product.
What is the safest sleeping pill?
No sleeping pill is risk-free. Newer orexin receptor blockers like lemborexant have lower dependence potential than older sedatives, but the right choice depends on your health and should be made with a prescriber.
What is DSIP?
Delta sleep-inducing peptide, a nine-amino-acid peptide isolated in 1977 that increased deep sleep in some animal studies. Human results have been inconsistent, and it is not an approved medicine.
How long does CBT-I take to work?
Most people notice improvement within 4 to 6 weeks. The first week or two can feel harder because of sleep restriction.
