Last night I had a headache that turned into a migraine. All the pain was in my face and the front part of my skull- nothing in the back. But it was annoying enough that I couldn't sleep. I was a little bit queasy and knew that if I threw up I'd feel better. I eventually did throw up- twice- and felt better and definitely when I woke up the headache was gone. I'm guessing the migraine was from having a beer.
