anesthesia
"I am 72. Had my 5th colonoscopy 2 days ago. Before, I always had Versed, which was wonderful. With propofol, I was out immediately, but awoke feeling disoriented and very scared, like coming out of a deep sleep when the phone rings. Got home and cried for an hour over nothing.Slept all day.  2 days later still having trouble concentrating and feel very tired and out of it, unfocused. Never again."
