I've got a "dry socket" on one of my wisdom teeth, which in short means that the blood clot fell out and the bare jawbone was exposed, causing immense pain. The good news is I went back to the oral surgeon today and he put cool drugs directly into the hole left by the roots, then refilled my prescription for vicodin. Huzzah.
And Matt, if you've gone this long without having caffeine, when you do have it again, it's going to make you feel all loopy. I cut all caffeine from my diet a while back, then had a Dr. Pepper like three weeks later and thought I was going to be sick. Not a pleasant time.
