I know he is under close medical supervision so he should be able to get things adjusted correctly at the chemical level. Vitamins and exercise are also good advice.
Thanks for sharing your thoughts with our FRiend.
Perhaps he should see a nutritionist as well. I had heard alcoholics lacked Vitamin B (not sure which one) along with others, I'm sure. Had a husband and two siblings who wouldn't quit drinking and they are no longer with us. I'm sure if they had gone to AA they would still be here. Their bodies couldn't take it anymore. Eat well, exercise, take vitamins and see a nutritionist.
