Back when I was drinking, I could, on occasion, control it for brief periods of time. I could go to a party and have what anyone would consider a "moderate" amount.
After a short time of doing that, however, I would inevitably boomerang back into destructive, out-of-control drinking.
So I couldn't control it reliably or long-term, no matter how much I tried. The only solution for me was to quit drinking entirely because ANY alcohol consumption worked on my head and convinced me that I was "OK" to drink. I am not "OK" to drink. It takes over my life.
Not every alcoholic gets sh*tfaced drunk every time s/he puts lips to bottle.
