Usually when I can't get to sleep (or back to sleep) it's because I'm thinking of all the things I have to do the next day or two. So, I make a list of things I have to get done. For some reason getting them on to paper and off my mind helps me relax and go back to sleep. If that doesn't work, I turn on the golf channel.

During my college years I used my economics text book as a sleep aid. It worked every time.

That sounds like a good idea, make a list. In my case, I can't sleep because of what occurred during the previous day. It would probably still help to write it down, summarize it, address each issue, etc.
