I normally stay up until 12 or 12:30 on Saturday nights, but I also like to have about 3 beers in me at that point and get really freaking sleepy. Also, I never drink during games because I'm a nervous drinker and go through about 96 oz of water during a football game. That would not work well with beer.
So I have to decide if I'm going to have a couple beers after the game (staying up even later), or maybe if the game is in hand, maybe start around the 4th quarter, or just do my normal routine and watch it on Sunday. My main problem with that is that I have no willpower when it comes to checking scores.
