Are there any methods that help one fall asleep faster?

I usually play games on my gameboy, particularly RPG's or turn based games like Fire Emblem. A lot of them are also cool in a way that if you just turn off the game, it will save your last position/move/turn, or at least you can generally save at almost any point if you suddenly have to stop playing.

Kind of embarassing, but I've fallen asleep playing a game, only to wake up about an hour later, and find that the game's still on lol. Usually though, I turn it off when I start realizing that I"m falling asleep, and then generally have no trouble dozing off for the night.

How long this takes me depends on how much is on my mind. Sometimes it takes minutes, one time it took 2 hours (got a lot of stuff done on Final Fantasy though lol), avg I'd say takes about 10-30 minutes.

Jam it back in, in the dark.
