Phillips milk of magneisium is what my GI put me on when I was first diagnosed IBS-C. Plus zelnorm and stool softeners. The MOM was mainly to help me to start going daily until the other meds started to work. I took 1/2 tablespoon per night and went to the bathroom daily but it was diarreha. By the time I was diagnosed, I had gotten hemrroids from living off of laxatives and so forth to survive. So the diarreha hurt my hemrroids so bad!! Now when I can't go, which isn't too often, I use an enema so I can get that natural urge on my own and it is a full stool when it comes out..easier on the roids! Sorry for the TMI!
