Not fun for everyone.

Nitrous oxide makes me paranoid. My dentist gave it to me once, and I wanted to jump out of the window--five stories up--until I pulled the gizmo out of my nose. I had the same paranoid reaction when I dove to 140 feet one time, and got nitrogen narcosis (too much nitrogen in your blood.) I'll never have nitrous at the dentist again (or dive deeper than 100 feet.)

Sorry, no info on the novocaine reaction, but it sounds scary.
