What's REALLY fun is when they're trying to numb you up and they hit the nerve. EEEK! that is like nothing I can even describe.

My experience with gas is that sometimes it still hurts, but I no longer care! I think it was my second root canal where I was lying there thinking: "I can feel that a bit. I wonder if I should say anything. Of course, that would mean I'd have to actually make noise, which would require effort, and really, I'd rather just lay here in this warm, floaty cocoon of not-caring."

Was this one of your bottom teeth? For me, those cause the worst jaw-ache.
