allow me to play devil's advocate....Isn't a 12 pack a day equivalent to having 12 drinks a day....?
it sounds different....are you drinking a 12 pack a day of light beer? n/a beer? or full octane....
I *only* drank 8-10 glasses of wine a day and w/d was not a pleasant experience....I had meds. just in case...but did it on my own...i don't know if I would do that again...very rough on my stomach.
be honest with your doctor and get a professional opinion....hope you succeed.
