I don't know if this would help anyone else, but I had diarrhea for about a month and a half straight and Citrucel got rid of it. I tried every over the counter anti-diarrheal you can imagine, as well as changed my diet, etc. I then began trying fiber supplements. Psyllium did nothing except give me gas. But Citrucel solidified everything overnight and it didn't come back again. I used the clear-mix. Good luck!
