Propofol
"This was my third colonoscopy, but the first time I received propofol. I didn't experience any pain at the IV site, I drifted off to sleep immediately, and after approximately an hour in the recovery room I was discharged. Unlike the previous colonoscopies where I had to go home and "sleep it off", I felt fine and alert after this procedure.

Now for the bad news. After I woke up I could recall feeling a " tugging sensation" in my abdomen, hearing conversation, and being aware of the procedure momentarily while it was going on. I didn't experience any pain. I would still give the drug a nine out of ten, although if I receive it again in the future I will tell the anesthetist about this experience."
