I consider myself an expert on headaches, especially migraines...I have discovered that my triggers are good chocolate (as in Godiva) and sauna baths. Chocolate only gives me a #4 migraine but a sauna will lay me out with violent throwing up and a #10 headache, both last for three days.
I avoid my triggers and take a combination of feverfew, Vitamin B2 and Magnesium Asporotate, after considerable research. Peg would be proud of me...good luck!
