Hello, I'm a 39 y.o. slightly overweight female who has suffered with G.I. problems for as long as I can remember. During my younger years, belly aches, then BM/diarrhea, at times accompanied by vomiting. At this age, here are the specifics: (diagnosed w/IBS - I don't believe it)I have one BM daily (no constipation), but at night, past number of yrs., 3-4x wk., I am wakened by sharp stabbing on & off cramps middle and lower, mostly towards left-side.
