Hi Fandy,
If you Google L-Glutamine alcohol cravings you will get loads of info. You get it from health food places. I take 1000mg once a day but it depends on the individual. Took me a bit of trial an error to get to this. I find it really helps with the cravings, making them much more managable. No need for the old white knuckles any more.
First one that came up.
