Eeek! Schedule a week off if you can...so the pretty, pretty pain drugs will work their magic and help you heal properly afterwards--and, ice cream or popsicles to soothe the areas after (we did it for Jay; apparently what works for removed tonsils and adenoids also helps with root canals--who knew? Your mileage may vary. Watch that the kitty doesn't share (too much!) ice cream with you^^
