I'm a binger and I can tell you I first got sober 16 years ago. In that time, I have relapsed 6 or 7 times, and I WANT to not drink. Can you imagine how many times a person who DOESN'T want to quit drinking is going to relapse if they quit?
His drinking low-alcohol beer may make you feel better but that is just him trying to control his drinking. An alcoholic cannot control their drinking.
