Some people have trouble getting relaxed enough to fall asleep, so they generally lay awake for longer before drifting off. Maybe try some relaxation techniques or breathing exercises. I find concentrating on breathing to have a sort of hypnotizing effect, therefore relaxing my mind. *

Make sure you aren't having any caffienated products several hours before bed, and make sure you're getting enough sleep every night.
I drink a lot of caffien so I should stop that... I usually get an hour less than recommended sleep :-/
