I spent a week in Georgia visiting a friend back in May, and one night I started drinking at about 4pm. Not heavily, just sippin a few beers, went to dinner, kept drinking, then went to a party at about 8. Drank 'till around 3am. went to bed, woke up wasted, and was still drunk the whole next day. It sucked major balls because after awhile you just want to be sober, but you can't force it.
