Migraine: a disease affecting women three times as much as men

Migraine (yes, singular, like cancer or depression) is a disease that's not well understood. Some say it can be triggered by caffeine, dehydration, or even weather changes. Then suddenly, there's a thunderstorm of pain, light sensitivity, and nausea. Women are three times more likely to suffer from migraine than men. It can spark anywhere from once every few months -- to every day.
