This is just personal experience, but I have a hunch that a lot of sleeplessness is also caused by weird schedules. In the weektime you get up at 6, you go out on Friday and sleep until noon, and then on Sunday get up by 10, and then back to 6 AM again on Monday. In high school and college, it used to take me about an hour to get to sleep, and I'd always wake up tired after hitting the snooze button for three, four times. Since about half a year ago, I've been getting up every day at 6 (week or weekend and in the first weeks of trying this out, whether you're tired or not) and all my sleeping problems have disappeared. To make sure I don't think about it, I hit the shower first and then decide whether I want to go back to bed... which at that point, you never do. Not tired. Easy to fall asleep. Don't need caffeine in the morning to stay awake. I know there's more to insomnia than just bad habits and I don't want to be the kind of guy who argues that sleep problems are "just inside of your head", but I do wonder whether the fact that sleep issues are so pervasive in our society might have to do with a lack of routine in most people's lives.
