It's been 25 years since the last time I had nitrous for a dental procedure, so I don't remember much about it. Today's experience was, well, interesting. What amazed me the most, I think, was the "don't give a crap" attitude that nitrous gives you. There were only a couple of instances of what would have been significant pain, during which I thought - "Oh, that was interesting." "Oh, hey! Sutures!"
