Well the Answer Man did it again. He explained to me that my issue of waking up extremely early after I drink is actually quite common. Apparently what happens is that the alcohol makes you sleepy and that's why you sleep so well after drinking it (duh). It's after your metabolism has cycled the alcohol out of your system that you wake up because your body is suddenly energized and on a high. And here I always thought it was the sugar in the alcohol kicking in!
