There was a guy talking on NPR about this a while back, it was a really fascinating conversation. He was talking about sleep hygene in general and actually answered a question that goobster and I were having about why boozing it up will knock you out but then a few hours later you're wide awake. Turns out it's nothing to do with sugar or anything, but the fact that alcohol works as a sedative and will put your brain into sleep mode even if it doesn't have enough sleep hormones built up for sustained sleep.
