I have a very mild case of IBS in that I'm really not constipated nor do I have diarhea, but I do experience all the other symptoms: switching between the two, extreme bloating, loud gurgling, somtimes feel like I have a fist in my abdomen near my navel, etc. I took IBSACOL (three-four caps) at every meal and felt little or no help at all. True, I only used one bottle, but I have no intention of buying another bottle if I didn't feel any better so far. Maybe I'm wrong, but I think I should have seen some improvement by now.
