Do any of you have sleeping problems??

I seem to....For example, I went to bed a while ago, and here I am awake, and now surfing the web as I can't sleep. The sun is coming up...it's like almost 6am. I have to get UP in a few hours..it drives me mad. Anytime I have to get up for a specific time (esp. if I'm nervous) I CAN'T sleep. I have enough trouble sleeping to begin with.

What do you do to help this?

Also, I could sleep fine, and I'm ALWAYS tired...any idea here?
