Lots of non-pharmaceutical options being suggested here, which is fine if they work. However, my wife suffers from chronic insomnia, and has tried many of these things, without much success (no jokes about the "sex before sleep" option, please; the sex is working just fine, but not necessarily as a sleep aid). She has also tried Ambien, and it got her to sleep, but made her feel kind of dopey after waking, which isn't so great. She has recently started taking the relatively newer prescription drug Lunesta, and swears by it; it helps her sleep, but it's not a narcotic, and she feels fine the next day. Might want to talk to your doctor about that one.
