I think I'm actually on the mend!
Last night I slept for about ten hours with only two wake-ups. My cough isn't quite as deep this morning, and more of my voice is back. I think today will be a day of soup and water and the last of the house cleaning--well, maybe not quite all of it, but at least a good bit of it. I have a huge mail pile to go through, my kitchen to clean, and some laundry to do.
Starting out the new year with a clean bill of health won't be such a bad thing...
