The minor headache of yesterday afternoon ended up becoming a full blown nuclear migraine in the early hours of this morning, pulsing bad enough behind my left eye that it made me nauseous to the point where I couldn't take any medicine to get it to go away because I would just throw it up if I tried. 
It was awful really and heatpacks couldn't only do so much.
I ended up taking two showers within the space of a couple of hours of each other, to try and get the muscles in my neck to relax so that the pounding in my head would fade.
That helped a bit. Enough that I was able to fall asleep. 
The headache faded after that, but didn't go away until I pulled out a mountain dew. The caffeine from that finally chased it away. So woot.
