Its not similar to orals and alcohol because the orals are taxing ur liver pretty hard by them selves, and then u add the alcohol = bad combo for ur liver...

anyways it has all been said above that alcohol reduces protein synthesis yadda yadda yadda, its all correct...

bascially if u drink in moderation (like 1 or 2 drinks a week) on the weekend, you should be fine, just be sure to do some extra cardio the next morning so u can burn off the calories u got from the alcohol...
