1. dim the lights and listen to calm, soft music. I prefer piano.
2. Look up Meditation at wikipedia.org, and meditate while looking downwards. It'll help you become drowzy.
3.I make a little something with room temperature milk (heated via microwave, not left out on the counter), vanilla, sugar, and a touch (just for a aroma) of nutmeg/cinnamon or somthing. That helps me get drowzy in a hurry.
4. relaxation.
5. Sitting up in bed, and taking a baseball bat to the head. Always be in bed when using this technique, and have asprin ready in the morning.
6. medication, such as cold medicine that makes one drowzy or sleeping pills, will help a great deal.
7. excercising during the day
8. Holding your breath until you pass out.
9. waking up at an ungodly hour in the morning.
10. eat a ton of turkey.
11. ingest so much caffeine that it backfires and makes you sleepy instead of more alert.
12. IV some sugar water into your system.

Just somethings I threw together that might you help fall asleep.
