Cholestyramine
"I had my gallbladder taken out 2 years ago, after 18 years of having stomach issues and pain and several doctor visits, they told me I needed to have the surgery and get my gallbladder taken out, then the doctor told me I had irritable bowel syndrome, he told me I would not be able to eat anything greasy because if I did it would go right through me, well I stopped eating greasy foods and ate grilled chicken all the time! It gets old, I started loosing weight, my hair thinned out, I got sick all the time and always had to cancel plans or call in sick because it would get so bad. I finally went back to the doctor and said you gotta do something I cant go on like this anymore and so he put me on this medicine and its worked miracles."
