Had a slight headache when I went to bed then things got weird. Woke up about midnight, went to the toilet, and when I got back in bed a had a bad case of the shivers and couldn't get warm. Threw on a a long sleeve shirt and went back to sleep. Woke up an hour later to use the toilet again (was told to really hydrate day of second shot) and the moment I got out of bed I started to shake uncontrollably. Was barely able to pee I was shaking/shivering so bad. Got back into bed and it wouldn't stop. I didn't really feel that cold but I was shaking violently (to put it into perspective, I once went fell into an icy Boston Harbor one winter and when I got back onboard I wasn't shaking nearly as bad as I did last night!). Grabbed another blanket and as soon as I got into bed I went from being slightly chilly and shaking to being too warm IMMEDIATLEY. Stayed that way until 3 when I started tossing off all the extra stuff and I was still too warm. Tossed and turned till 4 then tried moving to the couch downstairs. Never made it back to sleep. Now I'm on my 3rd cup of coffee and I'm that kind of stupid you get when your too tired.
For the record.... this is NOT your case... BUT... if you didn't have a good reason for such an immune response - those symptoms match the onset of a serious infection / sepsis. AKA, you would need to go to ER immediately. Remember that shaking. You never want to experience that randomly without a known cause.
