"I been through hell and back dealing with this stupid disease. I have a fabulous GI doc, who has tried me on a million medicines for diarrhea and pain from IBS: anti-diarrheals, anti-spasm meds, bile acid sequestrants (I have no gallbladder), tricyclic ADs, etc. None of them helped except this medicine. Seven years into this misery, and I've finally found the drug that works for me. I can begin LIVING again instead of only going through the motions. Please give it a try. My heart breaks for those of us that cannot find relief from this debilitating condition."
