I have a beer or two once a week to satisfy my craving...
My label did not say to avoid alcohol from what I remember off of the top of my head, and my GI said it's OK as long as you are responsible and drink lightly/in moderation.
Since I am newer to 6MP, I have admittedly slipped up being caught up in the excitement of celebration (friend's proposal/birthday) gone overboard twice since on this med....and I felt like complete CRAP the next day. Moreso than before I would take the med. I just felt disgusting and worn down, unable to move about and eat and leave the sofa much. **I must note that these slipup moments involved shots....I have learned now that shots aren't really my best friend anymore...
But a few beers once or twice a week has not done me any harm. My blood levels are all within range so far....I try to only drink every other week though when I can fight the urge and the occasion. That way I learn to live without the need to drink.
It sucks because I LOVE craft beers, and I am at the age where going out for drinks is the social norm.....but I am definitely more mindful about my drinking habits now. No matter what though I ALWAYS make sure to have plenty of water before, in between and after a few drinks.
