I get migraines infrequently. I can go years without one but when I do get one they are always debilitating, very severe with an unbearable headache, nausea etc.I need to lie down in the dark. My greatest fear is that I get one on a flight where there is nowhere to go, bright lights, noise and food smells which cannot be avoided. I just don't know what I would do if this happened. Has this happened to anyone else and what did you do?
