There are times where i know for a fact i could go to be really early, cause im really tired, but if i sit in front of the computer, that feeling now goes away.

Also, my sleeping patterns are also screwed up majorly, for other reasons. Stress, depression, being overly happy/excited, angry.. etc, all affect our sleeping patterns

Try reading a book rather then watching TV/Computer etc, or listening to some quiet music. It should keep you entertained enough until you can fall asleep : )
