All depends on the night. I can usually drink about 3-5 good sized Brandy & Cokes and be tossed. Or a bottle of wine...or 6 beers.
BUT, one time I ended up in the hospital with alcohol poisoning after drinking 1 beer, 2 shots of jack, and half a bottle of Hpnotiq in a 6 hour time span. The dr. told me you can have two beers one night and not feel it, and have 2 beers the next night and it could hit me.
I don't really drink anymore, though. Maybe one every couple of nights and that's it. I have a little man on the way, so I want to be as healthy as possible.
