It snuck up on me too. I was on the treadmill and could feel a headache coming on. Usually it takes headdaches to build up but this one is like someone struck me with a damn baseball bat.
I only managed to do a little bit of weight lifting and about 17mins on the treadmill before I had to stop.
This headache is piercing and just fucking awful.
Damnit, it figures, as soon as I start, I have to fucking stop.
Just took some tylenol and am about to go lay down. I'll start back up as soon as it's gone.
