Can't sleep

Why you can't sleep even though you're tired

• A mind that won't stop: stress and anxiety keep the alert system running.
• An irregular schedule: a body clock that never knows when morning is.
• Late caffeine: half of a 4pm coffee is still active at 9 or 10pm.
• Alcohol: sedates you to sleep, then fragments the second half of the night.
• Late bright light and screens: push your clock later.
• Long or late naps: spend your sleep pressure before bed.

The frustrating truth is that sleep cannot be forced; the work is removing the things that block it, then letting it arrive.

What to do tonight

• Awake for about 20 minutes? Get up, keep the lights low, do something calm and boring, and return when sleepy. Lying in bed awake trains your brain to associate the bed with frustration.
• Keep the phone out of the bed; bright light and interesting content both push sleep away.
• Set tomorrow's wake time and keep it, even if tonight is bad. The fixed wake time matters more than the bedtime, because you cannot control when you fall asleep but you can always control when you get up.
• Skip the nightcap: alcohol helps you fall asleep, then guarantees a broken second half of the night.

What actually works

• Fixed wake time every day, including weekends.
• The 20-minute rule: awake for about 20 minutes? Get up, keep lights low, return when sleepy.
• Bed is for sleep: no work, scrolling, or TV in bed.
• Morning daylight anchors the clock better than any supplement.
• CBT-I (cognitive behavioral therapy for insomnia) is the first-line treatment and outperforms pills long-term. Its most powerful and most counterintuitive piece is sleep restriction: deliberately shortening time in bed to rebuild sleep pressure.
• Melatonin helps timing problems (jet lag, a late body clock, shift work) at low doses around 0.5 to 3 mg, taken a few hours before the target bedtime. It is a timing signal, not a knockout pill, and the 10mg gummies on most shelves overshoot what the brain uses. Over-the-counter antihistamine sleep aids lose effect fast and leave a hangover.

When to get help

See a doctor when insomnia happens three or more nights a week for three months, when loud snoring, gasping, or witnessed breathing pauses suggest sleep apnea, when crawling leg sensations keep you up (restless legs, sometimes tied to low iron), when sleeplessness comes with a persistently low or unusually elevated mood, or when you are falling asleep involuntarily during the day. New persistent insomnia is often the first visible sign of anxiety, depression, thyroid problems, or perimenopause, and deserves a look underneath rather than just a pill.

Can telehealth help?

Very well, because insomnia diagnosis and first-line treatment are entirely conversation-based: sleep schedule, caffeine and alcohol timing, stress load, snoring history, and what you have already tried. A text consult can build a real CBT-I style plan (fixed wake time, the 20-minute rule, wind-down, morning light), screen for sleep apnea and restless legs, and check whether mood, thyroid, or medication causes should be tested. The part that needs in-person care is a formal sleep study when apnea is likely, and anything involving controlled sleep medications. For the large majority of "I can't sleep," text is not a compromise; it is the right venue.

What recovery looks like

Behavioral fixes work on a two-to-four-week clock, not overnight. The first week of a fixed wake time usually feels worse before it feels better, because you are rebuilding sleep pressure. Most people doing CBT-I style work notice sleep coming faster and holding longer within a few weeks. If nothing has moved after a month of honest effort, that is a reason for a clinician to look underneath for apnea, mood, thyroid, or medication causes.
