Quick update on yesterday, my first colonoscopy.
I declined sedation (benzodiazepine, the stuff that makes you forget most of the procedure ever happened). They did, however, give me an analgesic (just a little bit to relieve discomfort).....Fentanyl, a drug 100 times as potent as morphine. Apparently, some people find this opiate enjoyable, but after the initial hit (which was sort of a dizzy wave) I felt completely normal.
Fully, or almost fully, alert I was able to enjoy the roller coaster ride through my large intestine on the video screen. He took out two small polyps on the way out (they go in quite rapidly, most of the inspection is done during the slow extraction). Very minor discomfort, the USA is one of fairly few countries where sedation is the norm.
Afterwards, a broccoli, onion, and cheddar cheese omelet!
