Organized my icon folder on the laptop, and made some new icons. Put the ozonator on the furnace feed, which has made a significant difference in my ability to breathe, though my ears are a bit clogged. Napped from 2-6. Took a buttload of vitamin C. Cleaned the oven, or rather pushed the clean button, which starts a three-and-a-half hour cycle of self-cleaning. Or more to the point-- self-burning. Still feeling a little weak.
