Got my second shot last week. Hit me HARD early Friday morning. Felt like the worst case of the flu I've ever had in my life. Woke myself up shivering violently about every 30 minutes or so over the course of like 10 hours of attempting to sleep. X_x
That part stopped before I had to go to work, but I basically did nothing that entire night. Was mostly better by Saturday and 100% by Sunday so doing much better now. XD
