I was put on that for I bet more than ten years and it never did help. I felt like I had a low grade fever most of the time a sore throat and it makes you sensative to sun light and usually a skin rash at times.Have you thought about giving the calcium a try it can help control the diarrhea a lot better than any thing I ever tried.Let me know if you have question after you read some of the success stories posted.Linda
