I don't remember all the trauma from my oral surgery. The doc hit me with some gas and told me to count backwards from 100. I think I got to 90, and the next thing I knew my dad was helping me out to the car. A couple days later I was back in action. It was rather painless, as I recall. My teeth were impacted, so it wasn't an easy job.
All I can say is "Where can I buy a bottle of that gas?" That stuff was killer sweeeet.
