Root Canals and Laughing Gas

Today I had my root canal...or to be more accurate, part one of my root canal. I need to go back next week to finish it. As I type this, my mouth is still numb from the novacaine, though the laughing gas has probably left my system by now. Since i was given laughing gas however during the whole procedure I think my behavior was a little bit....off. I felt like I do when I'm hyper and giddy. Which basically meant I babbled a LOT. And when I couldn't (since they had my mouth held open) I started "singing" along with the music from the ipod I borrowed from CJ. Disney songs. The nurse started laughing at that. I also made weird faces when the novacaine started to kick in (I was already on the laughing gas for a few minutes before that). Overall wasn't so bad....though I really dislike being numb. And it's over. Till next Monday at least.
Add: Ok, once the novacaine wore off, not so fun. I felt like I'd cut my own my head off if I thought it would stop the pain. Instead I took advil and went to bed.
