@dommymommy the one time my family got the flu shot, I was 12 or 13, we were all completely put out of commission. I remember us all lying down on the living room floor with a movie playing and going in and out of consciousness. We basically took turns using the bathroom to throw up.

I got covid last year and it only got that bad for a couple of hours, never threw up either. That lasted days. My memory of it is foggy because I spent the majority of the time asleep.
