I had both doses already. I got the Pfizer, with the first shot on March 14 and the second one on Easter Sunday. Both shots done by 2:00 pm.
1st dose, sore arm on Sunday afternoon and on Monday I was tired but went to work. But Tuesday morning I went to work and after an hour, massive headache and the hit-the-wall exhaustion and had to go home.
2nd dose, no sore arm. Minor headache Sunday evening. Monday, I worked a full day with a mild headache in the background. Monday night, headache got progressively worse and Tuesday it was blinding and the exhaustion was back. I was essentially useless for 12 hours and went back to work on Wednesday, fine.
