I have trouble sleeping. i don't drink caffeine 5 hours before bed. i go to bed at 9 and wake up at 6. but it takes me 30-60 minutes to fall asleep.

Falling asleep: Can be helped by homeopathy quietude by boiron. Safe, inexpensive to be found in wholefoods or other health organic store. Other than having trouble falling asleep, your sleeping hours are very good. Keep this good night habit, good for you!

Sleep onset: Sounds like you're not satisfied with how quickly you fall asleep -- but once you do, you sleep through the night? So, is your room noisy? Tv/lights/computer still on? Room too warm? Pets wanting attention? Do you work out just before bed? These can all disrupt you. Create a relaxing evening ritual -- such as hot bath, soft music, gentle reading, etc -- preparing for sleep. See if it helps.
