anesthesia
"I had versed and propofol for a colonoscopy and it was wonderful.  I went out like a light and then almost instantly woke up afterwards.  I was not even sleepy the rest of the day and could have driven home (although it would not have been advisable). There was no pain upon injection and no soreness at the injection site.  Propofol was used as I throw up if I take any kind of narcotics or synthetic narcotics."
