Cholestyramine
"Cholestyramine Powder has saved my life.  In January of 2006 my Gastroenterologist was finally able to diagnose my stomach problem by taking biopsies during a colonoscopy.  For years, starting in the early 1970's, I had been told I had irritable bowl syndrome and controlled my flare ups by changing my diet.  But around 2002 my condition became so serious, I was fighting to keep 100 lbs. on my 5'2" frame.  I looked like a skeleton covered by skin.  My doctor and I tried various medications and I tried to control my stress.  Nothing was working until my doctor did a colonoscopy with biospies.  Now if I have a flare up, I use 1tbs of Cholestyraime Powder in 8 oz of room temperature water before bedtime and I'm good to go. "
