I get migraines sometimes. My neuro gave me a Rx for something called "Midrin". It's apparently an older migraine medication. It works great for me.

When I had optic neuritis a couple of years ago and my optic nerve felt like it was trying to make my eyeballs explode, the Midrin actually helped some. Didnt take it all away, but made it mostly bearable as long as I wasnt out in the bright sunlight.
