Whisky - during the "Christmas season" three glasses a night (about two American shots per glass).
Beer - happy hours with the boys, I can go through five/six beers without batting an eye. Weekends (particularly during college football (American) season - I can go through a 12 pack of beer during the course of the tailgate, game, and after party.
Wine - two/three glasses a night before, during, and after dinner. (when I'm not drinking something else).
I typically only drink whisky during this time of year, then put it down until next November-December.
