I've had a touch of nitrogen narcosis while diving. I believe you.
I saw a show a few years ago made in England where this guy researched the best way to die. He interviewed all these scientists and doctors and they went over all these different ways a person could die, how much pain is felt etc etc and eventually at the end of the show (which was like an hour long) they came to the conclusion that the most pleasurable way to go was by inhaling pure nitrogen. He then asked a prison warden why they didn’t execute inmates that way instead of lethal injection, and the warden said “Because we don’t want them to go out feeling pleasure” lol...I was like oh great, now the libs are going to demand nitrogen executions.
