That came out of nowhere

Wow. Haven't had one of those for a while. Headache so bad it made me nauseous. Not a migraine, it was all around my head rather than on one side, but so intense. I made it to work alright this morning, but around lunch time I just couldn't keep going. Came home, ate a bowl of cereal, took painkillers, then went to lie down for what I'd planned on being an hour.

I woke up half an hour ago. It's now 6pm. *facepalms* *gently* The headache has receded some, but my stomach still seems to be upset, and I'm freezing.

Joy.
