You’ll do great, Nancy. I was a little anxious waiting for my second as well, not knowing what side effects I’d have after. Everyone is different of course but my side effects with dose 2 of Pfizer didn’t really start till about 36 hrs post vax. Low grade temp and slight chills for about 12 hours, then was back to normal. My parents all had Pfizer and their experiences were similar. It will be fine! Just remind yourself it’s a sign your body is developing the needed immune response to the vax. And even if you don’t get side effects, that’s ok too! You’ll be well protected. The breakthrough cases are extremely few and far between.
