For pretty much my entire adult life, I've woken up multiple times in the night--usually five or so times a night, starting from about 1-2AM and going every hour, give or take, until the alarm goes off. I quit caffeine, I sleep in a dark room with only white noise, I live in a quiet neighborhood--I am just a light sleeper. I've recently been taking magnesium supplements at night, and so far have noticed no change. Melatonin doesn't help. I'm seriously thinking about getting some Ambien or something. I go to bed at about 10:30 most nights, the alarm clock goes off at 6:00...I can fall asleep just fine, but staying asleep is a big problem for me.

Any tips?
