2-3 drinks per night is extremely unlikely to have a measurable effect on your strength. Might be a slight positive if anything. That hasn’t only been my experience, but the experience of many others. People mentioned Jamie Lewis and Layne Norton. Besides those two, whose experiences are well documented, many strength athletes of yesteryear considered beer a post-workout recovery drink, and I believe some recent research has supported this practice. Go digging if you’re interested. Also, Art Devany, who was ripped and muscular and could dunk a basketball into his seventies routinely drank beer with his dinner. Anecdote =/= data, but you know, patterns emerge.
Getting smashed will probably have a deleterious effect though. Further, I think being lean is an advantage here, as it’s easier to recover from drinking, or pretty much any minor insult to the body, if you are lean. But in sum, worrying about the recovery hit from drinking is probably going to impair recovery more than light drinking itself, so I think you’ll be ok.
