Hi, A few days ago , I had Reflux at night after a heavy late meal, I took 3 Gaviscon Tablets and a PPI , the next day I felt sick all day , but did not vomit , I ate lightly , But last night and this morning I passed a pale mustard Coloured stool , firm at first , but quite watery this morning . Is this anything to worry about ?. Did I just over do the antacids ? How long do you think before my stoll returns to normal? Thanks.
