Really glad to read you are taking today off, and strongly of the view that others have expressed about taking it very carefully and very possibly having tomorrow/the day after off too, or at most doing half a day. I had Covid over Christmas, when at least we were closed so I didn't have the 'should I work?' dance, and kept thinking I was definitely feeling better - which I was - then doing one thing, and not a very tiring thing, like hanging up a wash, and having to have a nap to recover.
