I like how posting is back and we're not doing much with it, lol.
So anyway, who else has gotten a covid shot? I'm getting two. I've already gotten one. I'll get my 2nd shot next week. Can't wait to have another sore arm. 
I got mine back in March/April. The first was fine and I only got a sore arm. The second one knocked me on my ass. Aside from already being petrified of needles, my arm was double sore (I flinched when they did it and the pain traveled all through out my arm), and I felt like absolutely crap for a few days afterward.
My advice to you is;
1) Don’t flinch like my stupid ass did.
2) Plenty on Gatorade, water, Tylenol, and rest after it.
