In my "prime" I could down a fifth and a 12 pack in a night and still function though I was definitley drunk.
Now I don't drink very much at all and might polish off a 6 pack around the campfire but last year I did down a fifth of gin in one evening at Goldendale and felt like hell for the next two days.
