Yes I did have gas today not to bad mainly this evening. I took 600mg at breakfast and was ok took another 600mg at lunch and felt sick to my stomach for about
an hr or so but I took another 600mg after dinner and so far feel ok. Not sure why the one at lunch made me feel that. It is calcium carbonate. I heard that is the kind to help with diarrhea. I am on Colestipol but my doctor is the one that told me to start taking calcium he just didn't mention what type I just knew. I don't take any other vitamins at all. Has this helped you to where you don't have to take any other meds for your diarrhea?
