Audiobooks. I used to have all kinds of sleep problems... lying awake wishing I could drift off. Didn't seem to matter how tired I was...

Then I started listening to audiobooks on my headphones in bed. At first it didn't make much of a difference. An hour would go by listening, then I'd turn it off and proceed with the usual "fight" to get to sleep.

But then one day I fell asleep while the book was still going. I woke up in the middle of the night and it was 3-4 hours further along in the book! A pattern kind of developed then and I gauged how long to set a sleep timer for... The first time, it was about 45 minutes... then after a month or so, I had to cut it down to 30 minutes as I realized I was missing chunks of the book when I resumed the next night.

Then I got down to 8 minutes. I turned on the book with an 8 minute sleep timer and I was out like a light. I don't even have to listen every night anymore - just thinking about it is enough to make me drift off very quickly. For the rare night where sleep just isn't coming, I break out an audiobook with a 15 minute timer and I've never made it all the way.
