Has anyone tried to use this to manage diarrhea? I take Immodium on a pretty regular basis to prevent accidents, and was wondering if anyone has had any luck with this? Unlike the intestinal formula 1, this stuff actually slows the bowels and solidifies it, which is really what I need. I've only used it twice, and once it worked and the other other time I had diarrhea, but the second time I didn't take near as much as I did the first time, which may have been the reason why it failed then.
