Replying to drinking problem

i woke up today and i felt like complete dogshit. i had to really concentrate on not vomitting in my 12:00 class, my only one of the day. i was thinking, what the fuck, i didn't even drink very hard last night. then when i thought back to how much i had drink i realized i killed a twelver of pbr and three keg beers. since when did going 15 deep turn into an easy night of drinking for me? i have an intense drinking problem i think. i've been trying to cut back lately because i seem to black out every other time i drink, which is two or three nights a week. i might die soon.
