A personal note. Some of my distraction and lack of focus (and missing deadlines; an apology to my editors) lately has come from a truly irritating toothache that had me popping 800 mg of ibuprofen on a regular basis. I found it hard to concentrate on most things requiring serious thought. It also made drinking cold beer extremely painful.
It was a cracked tooth, and I finally had it dealt with this morning. I've got about a day of pain to get through yet, and then I'll be good. Whew.
