When patients ask me what one change would help them most, my answer is almost always the same. Sleep. Not because sleep is glamorous, but because every other intervention — therapy, medication, exercise, relationships — works substantially better on a brain that has had its housekeeping done.

Even one short night raises emotional reactivity, narrows attention, dampens memory consolidation and amplifies threat perception. Three short nights in a row and you have a brain that is, functionally, running an anxiety filter on every input.

If you've tried 'just go to bed earlier' and it hasn't worked, you're not lazy — you're up against a conditioning problem. The bed has been paired with worry, with phones, with replaying the day. The fix is not more discipline; it's stimulus control plus regulation. That's the heart of CBT-I, which I integrate with CR for almost every insomnia patient.

First, decouple bed from worry: if you're not asleep within 20 minutes, get up, sit somewhere dim, return only when sleepy. Second, fix the wake time, not the bedtime. Pin the morning anchor and the rest of the rhythm starts pulling itself into shape.

If insomnia has been with you for more than a few weeks, take the ISI on this site, and let's talk.
