>>The only part of it under the control of the victim is to...
I cringe at the use of that word (victim) in this context. As if someone did something to someone, and someone else owes sympathy and restitution. The victim isn’t the alcoholic... it’s their family members and others who suffer from the effects of the alcoholics poor decisions. The alcoholic is the victimizer of their own family and friends. Once he can look at it in that context he is free to own and fix the problem.
Then, there are folks with liver damage from non-alcohol related causes and they could become alcoholics as well because of the damage.
Best bet is that if you have a Sa'ami ancestor you know about, or a Sioux/Lakota Indian ancestor, who was an alcoholic, you should not consume alcohol under any circumstances ~ EVER!
