My husband had the same side effects from pfizer. Flu like symptoms, crazy nightmares, extremely sensitive to temperature. He was so weak I had to help him do simple things like open bottles that the seal was already broken. He's gotten sick maybe once since we've met and as a former marine got all sorts of vaccines but this one was catastrophic. I'm high risk and know I'm going to have an even worse reaction if he reacted like this. Scary shit.
