I don't know what kind of drugs they use to stick a camera up someone's ass, but I've had to go under 3 times in the last ~1.5 years for dental stuff - only time in my life I've had to go under. Whatever that cocktail you guys use is fucking magical. "We're giving you the good stuff now." Seconds later...zzzzzz. I'd time travel and randomly remember bits an pieces here and there...like maybe 20-30 seconds every half our or so between getting knocked out and waking up in my recliner at home 3 hours later.
