The only thing that will make him drink is untreated alcoholism. Strangely enough the circumstances in which he now finds himself were the same for me, and that resulted in me sincerely taking action to treat my alcoholism. My recovery started by talking with a recovered alcoholic from AA one Sunday afternoon. He didn't charge me anything. Within three weeks I had taken my last drink.
Sometimes it takes serious consequences to prompt us to take action. Folks like me don't seem to be able to honestly see the problem until everything has gone down the toilet,
