There are 4 people in my immediate family, two of which have been alcoholics. (I use the past tense because one of those two is deceased, though in no way related to alcohol abuse.) I'm a third person, my mother is the other one, and I discovered that when I was a child both she and my father experimented with hard recreational drugs. I'm the only one in my family who hasn't done anything of the kind, and frankly having watched these people during the times when they used and abused chemicals, I can say beyond a shadow of a doubt that it did not contribute to their gaining and iota of happiness. Not one.
I'm sorry, but given a choice between aching loneliness and slowly destroying your body, killing your brain cells, and turning your innards into pulp, I'd choose aching loneliness. Seriously. There are other ways to meet people besides screwing with your chances of long-term existence. I just can't think of anyone I love that much that I would willingly take sledgehammer to my insides, even in a metaphysical sense.
Don't do it. Find another way. Any other way. Choosing between lots and lots of drinking and anything else is like standing on a track while the train is bearing down on you--it doesn't matter which way you jump to get off the track, just get off.
