Ugh! Second shot was worse than the first. Woke up shivering so hard the bed was shaking. Couldn't get warm. Have felt crappy all day and still cold. Thankfully I'm done with shingrix now.
I had those awful chills too, made my teeth chatter both times. Felt pretty much ok the next day, just a slight headache. I'd do it again though if necessary to avoid getting the shingles.
