Are you taking anything else besides the carafate. A PPI?
Have u been tested for H. Pylori?...it is not uncommon for those post op from a Gall bladder surgery to develop this and can be missed the first time u r tested...so push for a test....next, look at the meds u were on, u may need a probiotic to restore the natural balance to ur digestive tract....Talk to ur GI dr.
