Alcohol is one of the addictions that mlcers will pick up during their journey, just as some will discover porn, drugs, op, etc. It's self-medication for them. I would suggest that you not speak to him again about the consumption because it will fall on deaf ears. He's going to do what he wants and when he wants. He looks to you as a "mother" when you suggest he changes his habits/ways.
Step back, detach and try not to get sucked into his drama. Have you read any of the links that Cadet has out there on mlc?
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
