Not too chipper here, I was fine all day, went to bed at 23.00 and woke up at 01.00 with uncontrollable shivers.
Had some water and two paracetamol but could not get warm, put on a thermal base layer and shivered under the duvet for a couple of hours. Finally warmed up at 03.00 but by then my brain was running at 100 mph. Dozed off around 05.00 and woke up ravenous at 06.30. Been tired and lethargic all day now.
Speaking to friends of my age group (66) this is fairly common with the AZ vaccine, mostly men. Mrs Domus has had no reaction at all and is fighting fit.
