The head yanking went well, but I'm sure I'll screw up my neck again within just a few days. I fell asleep on the couch again (and thus no update last night) and my head was crunched up against the arm rest for a couple of hours. That's never good.
Now I'm going to go out and sit in the garage with the door open and listen to the rain for a while. It's not as terribly cold as I'd expected it to be, or as it usually is during a big rainstorm, so this rare opportunity must be grasped.
