Over the last year or so, I have significantly lessened my consumption of alcohol, and it has greatly increased my quality of sleep, but I was never one to oversleep because of drinking anyways. I will usually wake after only 4-5 hours after a night on the town. My biggest issue is getting to bed on time those nights ;) .

One thing that does help me out when I drink is to stick to spirits like whiskey and vodka. Beer seems to have much more of a draining effect on my body as do any mixed drinks with sugars in them.
