Dicyclomine
"I'm 28 problem started when I was about 22yr. old. I took dicyclomine for about a week for my Colon. After 3rd MRI spent 2.5 days in hospital. Only for them to tell me we don't know what is wrong with you here try these pills. They sent me home I had to crawl on my hands and knees vomiting along the way from hospital exit to my car. The pills (20mg) helped after about 3rd day then they seemed to make it hurt. Now I only take it when I can feel my colon starting to hurt it seems to work good that way. I'm still taking it."
