Hmmm...I was the opposite. Daily drinker, but never got drunk (drank small amounts at various times of the day starting in the morning). I never had trouble falling asleep, but would wake up after 3-4 hours and not be able to go back to sleep (which would prompt the middle of the night drinking). Since I quit...I sleep like a baby all night:-) Good amount...about a solid 8 hours. Haven't noticed needing more than that.
