Personally, I don't mind if people get drunk, as long as they can still walk, have some judgement remaining, don't start fights, don't break windows, don't bang cars, don't throw stuff, don't get himself and friends kicked out of the pub/bar/club, and don't need us to babysit him/her for the rest of our night.
While I don't do it more than once every 6 - 8 weeks now (estimate), I have drank until I've become tipsy numerous times. Sorry that I fit some sort of bad stereotype, but I do drink, and when I go out to a bar with friends, I rarely limit myself to 2 or 3 drinks unless I have something important to do the next day. However, out of my own judgement, I usually just go home at around 1 AM or so (because I live so close to the "city"). Just don't do the things I mentioned before, and your drunkenness is tolerable. Otherwise, you're a pain in the ass and a liability to all your friends.
I feel and am the same way, but I'd back that 6-8 weeks down to more like 2-4. (its hard to not be drinking at rugby games/parties)
