Yea this was me. Here is my reaction I sent to my friend. For info I work night shift at my hospital:

7 am Saturday got the shot, all was good. 7 pm started to get chills and was very tired despite having ok for night shift sleep. No fever. Went into work at 10 pm, very tired and cold. Laura took her lunch and honestly her 30 minutes felt like an hour. About 1130 I’m struggling bad and go home. Got home had a fever of about 100.1 F. Started to get achy and was still cold. Suffered that way until about 8 am and suddenly I felt much better with no fever but had a headache and muscle soreness. Went to sleep. Woke up at 3 pm and had chills and aches again, low grade fever was back. Called out of work. About 3 am started feeling better. By 8 am everything was gone but had a headache. Worked last night and was fine except being a little weak. Totally fine now. So those 36 hrs sucked but much much better than covid for sure.
