I'm with Juan on the Melatonin. I don't have a problem falling asleep, just staying asleep. This stuff really helps (me) YMMV. Also, the only side effect I have is very lucid (very) dreams. Can't complain. If you have trouble falling asleep, try the breathing techniques mentioned. I can't even make it to 10, before having to start over. Also, not a cheap solution, but you might try testing a used Biomat to see if it works for you. I usually wake myself up after 20 minutes with the snoring.
If I can get 6-7 hours of solid sleep, I am a happy camper.
