"I had my first colonoscopy today. I used OSMO PREP and was concerned about taking so many pills. After the first phase, I was a little nauseated, but my doctor had given me Zofran which helped tremendously. 
I was given Propofol during the procedure, and did not feel a thing, or remember a thing. I had no side effects from the medicine whatsoever. This was the way to go for me."
