I think anyone who has ever had a migraine and my husband will kill you. That helpless "I can't fix you and it's making me so sad that I can't" would probably do the trick in any case.
I stopped birth control pills and caffeine a couple years ago and that helped tremendously. From 1 or 2 a week, with a definite for sure 3 day monster around menstruation. It cut it down to 1 a month.
Once I switched to full Primal, I had one because I donated blood. But that's it. I have been doing really well since then. I've also started doing Crossfit and really heavy exertion used to set me off too. And sometimes orgasms would do it too. Since switching, no exertion or orgasm migraines. If I would have known that going primal would have fixed me, I would have switched a long time ago.
