Hey man, right here with you feeling rough after jab #2 :) The roughness is your immune system, not the spike protein itself per se, which is why jab #2 makes you feel a lot rougher - your immune system goes ape the second time.

A little perspective - one way or another, we're all going to be exposed to this damn spike protein eventually, and the vaccine is by far the safer way. If it does do something bad, we haven't noticed it yet, which presumably means it can't be that bad. I haven't seen any reports of people getting long covid from a jab.
