Cholestyramine
"I have had chronic diarrhea for the last 26 years.   I have tried many, many different medicines, but none helped me except this.   I cannot believe how good I feel now.  My whole life consisted of knowing where the next bathroom was.  I was prescribed to take this  2x a day.  The following day after starting it, my diarrhea has stopped completely!!   I am now starting my second month on the medication and I have had no side effects and absolutly no problems.  I sure wish I had this many years ago."
