Is my consumption of alcohol crazy as hell?

So to start off with I know I have a problem. I’m around 6’4 and 250 pounds and when I’m actively drinking I drink around 12-15 beers a night.

I come from a family where even the light weight women could put it back so I don’t have perspective on what SHOULD be normal. My friend can get shitface drunk off of one and a half Seagram’s spiked.

So is this something that’s out of the ordinary even for problem drinkers/alcoholics? (I don’t really see a difference in the two labels)
