I've always had problems sleeping, so I barely ever get enough sleep. I've always tried going to bed early, to get more sleep, but that never works, since I can never fall asleep, and I tend to stay up until at least around 2:30 or so in the morning, before I can actually fall asleep, only to wake up again in 3-4 hours later because of school.

I think one of the reasons why this is, is because I have the same problem as Meier Link. My mind keeps me up, from thinking a lot. And sometimes because of this, I have pulled all-nighters.
