I have also spent zillions of hours, it seems, studying !@#$ alcohols, which I thought I had a grip on from the first test, but apparently not. Final's tomorrow at noon. Boy, do I have work to do.
Amazingly, despite insufficient sleep, I got everyone supplemented this morning, and the cats fed and watered and given clean litterboxes. Food got made last night, so I have lunches to bring, and good progress has been made at work. It's amazing what I can get done once the PMS lifts.
