I can't sleep..Need HELP !!

[ithehappy]

this was problem for me. I won't feel sleepy till 3 or 4 in morning. Now college attendance is only 40% because of this. I am slowly changing this habit. Its really hard

The only thing which worked for me was putting extreme pressure on my brain, to the extent where it'll become very tiring, any way it works for you. Reading a book, playing a game, whatever...
Sometimes it's a good thing to be dumb really.
