Reb Rage, leave the poor girl some anonymity! :D :D :-\
TO - you should try listening to music - it gives you something to listen to while you're lying in bed tying to get to sleep, but it's not so involving that it'll keep you up - at least, that works for me. You just have to 1) get headphones that won't get in the way or hurt your ears, and 2) make sure your mp3 player is in a safe place so you don't knock it off your bed!
Shiurim can also work - they're a bit more involving, but you can allow yourself to drift off. And of course, there's the added benefit of listening to a shiur! I can recommend some good ones (in my opinion) if you'd like.
As far as while you're sleeping, I'm not sure what you mean - but here's something you can try: As you're relaxing to go to sleep, think positive thoughts, good thoughts, spiritual thoughts, etc. I used to do this when I had roommates, and I was terrified of what I might say in my sleep while I was dreaming! :D ;D
For relaxation exercises...I'll post that on your thread, cuz I think I'm going way off topic here! :D :D
