I don't drink, but it's ok if I date a guy that does. I guess to an extent though... a drink or two with pals is one thing. Getting completely smashed is a no go. I don't want to be cleaning up his vomit all the time, and I would be seriously concerned for his liver. Drinking rarely or occasionally is fine... if it's in moderation, then no it's not a deal breaker.

It could turn into a deal breaker if you do it to excess
