It depends... sometimes like every 2 weeks, and sometimes I'm not drunk for 3 months.
I try not to have those memories missing when I drink, and puking isn't so nice either... But drunk is drunk, eh?
I've only got to the puking-stage of drunkenness once, and didn't see what all the fuss was about so I don't do it anymore. I don't get to the tripping-over, slurring-speech stage very often either, mostly it's just three or four pints to make me laugh more than usual.
Back in University, I was getting heavily loaded 2-3 times per week, and "casually" drinking most other days. In med school I cut down considerably, getting seriously loaded once per week, drinking sociably 2-3x/week.
Since getting married, I only get loaded once every couple of months, although 2-3 times/week I'll still have a beer or glass of wine or two.
For me its about once every 4 or 5 months. So i'm not going to get drunk for the next 4/5 months.
I damn hate these parties where you drink more than you can handle
Used to get drunk more often then 3-4 times a week. Then I ran out of money and maybe got a chance to use a little bit of my brain. Now I drink once a week, maybe twice.
