anesthesia
"I had a colonoscopy/egd done twice, the first time they used versed/Demerol.  I had a bad reaction to the Demerol.  Then I had another egd done this morning and was extremely anxious.  The doctor gave me propofol, and all I remember was me asking him if he put the meds in my iv yet and him saying ya.....before he could finish I was out and the next thing I remember was waking up in the recovery room feeling a bit loopy, but no side effects.  I asked my wife later when we got home if they even put the scope in me.  It was a very pleasant experience and one I would get done again if I had the same docs."
