I'm so glad to know that I'm not alone! At work, I chose a cubicle that was as far away from a light as possible, but it wasn't enough. I had to have them unscrew the flourescent lights above and buy a lamp to work by. It still didn't help, and I've been on medical leave for the last 6 wks. I, too, have dark sunglasses that wrap around and even wear them inside when I feel a h/a coming on. My husband drives me at night if possible, since headlights/taillights also trigger my migraines.
Thanks for posting this ~ I wish you luck in finding something that will work for you.
