Can someone recommend something can help me fall asleep. I am so damn sick and tired of taking like 2 hours to fall asleep. I don't know whats wrong with me. It's just really pissing me off now. I'm trying to get a good night sleep before an exam I have tomorrow morning, but that won't be happening.

I keep getting to the point where I'm about to fall asleep. Then I snap out of it, and I'm really wake, and its like WTF!!! why does this happen (sorry, I'm just not a happen person right now)

I'm about to start staying up 2 days straight if thats what it will take me to fall asleep when I want to.
