I probably would not take immodium whatever is in there must come out. I am also having a lot of stomach and back pain and bloating but not much BM at all and very painful when it does happen. I am at the beginning of my second week and I think one of the herbs from dr clarks protocol must jumpstart the colon and causes the cramping.I think everyone symptoms are a little different depending how infected they are. and types of parasites. I am barely going to the bathroom so i do not know what to think either I believe I have parasites and would like to get them out preferably by bm. I reduced my herbs because of the pain. Maybe that will help you too.
