Busy doing nothing

I seem to be having a bit of a reaction to the COVID booster vaccination we had yesterday. Naturally, Mr. Beewatcher’s as chirpy as a cricket, but I’m sitting shivering, absolutely unable to feel warm, and my poor arm is aching.
I looked up the  effects of the vaccine, as you do, and the first one mentioned was chills. Well mine are certainly multiplying. 
I’ve got a crossword and a cosy crime novel if I feel up to either, but I think it’ll probably be a hot water bottle and an early night for me.
