Guess it would depend on how much, I don't drink often, last time was a few weeks ago (before that years, other than a hard lemonade here or there) but some friends came back from a vacation\Wedding of a friend and has some stuff we finished off I had about 6 shots of Patron Vodka, 4 shots of some other Vodka, two long islands, and a few Seagram (3 regular and one screwdriver), laid down around 1:30am and woke up around 6am and felt fine. (not sure if that's consider a lot or not again not normally a drinker)
