Sure it does. What medical treatment did you receive for your alcoholism, and what ongoing medical treatments do you undergo to remain sober?
And your comment is like saying abstinence isn't an effective cure for pregnancy. (even though it works every time it's tried)
Actually, my point is that abstinance IS an effective "cure" for pregnancy. But abstinance isn't a medical treatment -- it's a matter of controlling your behavior.
Might as well try to argue fine points of theology with an atheist.
