Cholestyramine
irritable bowel syndrome
"I just started on the powder form of this medication. The first night I gagged on it, but managed to drink it down at around 3pm. I felt so much nausea that I wasn't sure I wanted to continue, but the next day I felt no urgency, had a normal bowel movement and felt no nausea. I slammed down the whole drink and didn't gag the following few nights. I'm so glad I didn't give up and continued to take cholestryam."
