IBS

I have tried about everything to get rid or ease the symptoms of IBS. I have had a colonoscopy, celiac test, ultra sound on uterus, endoscopy, food allergy test, etc. I had my gallbladder removed and that helped some. I have tried probiotics, dicyclomine, imodium, colestipol, staying away from wheat and corn products. Right now I am taking Aloecure and that isn't helping. Nothing seems to help ease the symptoms. Imodium will take care of the diarrhea when that is the problem but I still have to deal with multiple bowels movements and feeling of still having to go all day long, every day. Does anyone have any other ideas of what a person could try?
