Idk how people become alcoholics. Alcohol is absolute murder on my stomach even when I only have small amounts (no matter what type of alcohol...seltzer, wine, beer, hard liquor). I do drink when I'm sad, but I hardly have enough to get buzzed and I wake up the next day wanting to puke my guts out.
My mom will have like 2-3 beers every night. If I did that every night, I'd be puking and shitting all day.
