First Covid-19 shot

Well, I folded and got mine today. J&J one and done. There is a concert in a month that wife would like to go to so I capitulated. She got her $50 gift card today a week after her 2nd shot. F yeah, I felt it......Not sure if the J&J takes the same needle or cc as the other double dose shots but to say its painless is uh....wrong. Upper arms a little 'foggy' now. Don't expect much discomfort. Any one tell me differently? Doesn't matter now as I already got it. Stay safe........Im one of them now.
Kudos to you, you will be fine.
