I also have been diagnosed w/IBS for 25 years. This is a catchall diagnosis for whenever they can't be bothered to test for what's really going on. My new MD has attributed mine to GERD, but the gall bladderectomy is not helping your case. My fiance has had that and finds it kicks up periodically. You will need to get that process working with diet and the chemicals that help you replace the gall bladder in the digestive process. Good luck
