my father claims his doc told him he could resume drinking his beer 2 weeks after the removal of his gangrenous gallbladder. my dad has been drinking for 50 years. he also told his doc that he was only having 2 a day. he drinks 6 plus beers a day. is this safe? Alcoholism runs in the family and my dad is in deep denial about it. plz respond ASAP as his family is desperate to save from himself. thanks, angela bootz
