I have made it to 1:00 without any pain medication. That's nearly twelve hours. When I walked to the cafeteria for lunch, that little bit of exertion set my jaw to throbbing, but as soon as I sat down and rested a little, it went away. Amazing. There's been a definite pattern to the pain -- none or little when I wake up, hurts like hell by bedtime -- but this is the first time I've made it past lunchtime completely on my own.
