Update: I called the office, and the doctor was only going to be in for 2 hours. I wasn't about to drive, and had no ride, so I had to suck it up and take some more Advil.
At this point, a few days later, I haven't taken anything for the pain since as it's been manageable. I can swish water and Listerine now, so I can basically eat what I want as long as I rinse afterwards.
I'm still just a little sore when I make exaggerated movements (tighten the corners of my mouth to smile, sneezing, yawning) and my stitches come out tomorrow. Good thing too, they're starting to bother me.
