A friend commented on the original post: An article in the original Prevention magazine said. Alcoholics are seriously deficient in B vitamins. That deficiency gives them the urge for alcohol, when in fact they are craving B vitamins. The more alcohol, the more cravings. Giving one man B vitamins daily helped him get off the binges. And stay off. I am no scientist but if you love someone who craves alcohol, give them B vitamins daily. It does take a while. And, certainly won’t hurt him/her.
