If you are a woman, you need to take 800 mcg folic acid daily, because alcohol increases the risk of breast cancer, but folate offsets that risk.

I have also heard that a high protein diet helps reduce alcohol cravings.

and, of course, when you do drink, make sure to also drink non-alcoholic beverages, with a 1:1 ratio (1 full glass of a non-alcoholic beverage per each drink) as well as a complete, balanced full meal. those are the basics of the alcohol consumption hygiene, just to make sure you know them all. And practice, too.
