So.... I had a slight headache from the moment I woke up.... after getting to work it's only gotten worse. It's at the point of a migraine. I'm having a hard time keeping my eyes open because of the light, and it literally feels like someone is squeezing my head.

I feel like throwing up, but don't have any medicine, my coworkers don't either and I don't think I can drive to pick some up during lunch. Ive been drinking plenty of watwr. Any tips/ideas?
