i am not a partier. i only drink about 4 beers per month. But i noticed twice in the past month, the next day after having drank a few beers, when i rode my bike, I knocked about 10 minutes off my weekly 50 mile ride. Do any of you drink, and if so, have you noticed your performance on your bike is better the day after having a couple beers?? i mean 2-4..
