Hi Holly
From personal experience with my A, he can't drink responsibly. A couple of beers at home a couple days a week, led to drinking a quart of 100 proof every day. I don't think many could make the change. Heard a speaker at a AA meeting and he said 1 O'Douls set him back to drinking. I guess it depends on the person. But in my opinion I don't think it happens often.
Take care.
Many hugs.
Love
Debbie
