Young metabolisms can handle drinking and working out....We all know guys who have done that. Problem is, it doesn't last long. One eventually wins out over the other.
I was thinking as I read your first post about 10-15 beers, 3days/wk or so. I assume it's not light beer so at let's say, 140 calories a pop (conservative for regular US beer), that's 1400 ro 2100 empty calories a night! No wonder you're seeing your abs again.
There are few things worse than beer for lifters: they are high carb/empty calorie. Plus, people will drink a "few" drinks, but no one drinks a "few" beers, especially college age folks. I've had friends who did nothing else but give up beer and lost huge amounts of weight.
Anyway...well done gman.
