The Covid-19 vaccination I got Friday has been kicking my ass all weekend. I overslept yesterday and missed taking my mom on our usual Saturday morning walk in the park. (We tried after lunch, but the area we normally walk in was closed off for a bike race.) Then last night/today I slept 10 hours, and still have the sore arm at the injection site. I suppose I should be thankful for the clear indication that it's working.
YES. I got both flu and Pfizer on Saturday and CANNOT stay awake, even two days later. I almost never react to vaccines, so it was surprising. I came home from work today and slept 2.5 hours and could honestly fall asleep again right now.
