Looks like I had low-grade flu Tuesday and Wednesday. But today the fever went away (it tried coming back briefly this morning when I was still home, but went away and stayed away) and I braved going to work. I got eight hours in, keeping myself as clean and hydrated as possible -- hot tea, water, hot spiced cider and, by late in the day, straight hot water -- and I managed to work. And take it reasonably easy.
Still sniffly, but I feel like I'm past the worst of it.
And once again I'm reminded that writing about being sick is almost as boring as being sick.
