Man I had a cracked tooth that needed to be pulled and I'm gonna be honest while I was on that gas was one of the best times I've ever had. I honestly felt laying back in the seat staring up at the light that I was in some kind of sci fie movie the phone ringing in the back ground sounded weired as crap, the dentist came in didn't even say anything funny started laughing it wasyeah they said they are gonna use both on me...so how does the laughing gas feel
