I have’nt been fall-down drunk since my HS days, so maybe I’m not the best person to comment.
That said, I only allow the bottle to come to the table on friday night, afte rthe fish. And beer is only for shabbos day meal, and only if 2 or more people are going to share a bottle.
So I guess the rule of thumb we use is, MODERATION. Every day. The folks that run into a “drinking problem” are not drinking in moderation.
