It has been a long time since I had a migraine. Usually, I get the aura first, bright flashing sparkles in my eyes and I know it is coming. I try to calmly wait for the aura to pass in about 20 minutes and see if the headaches comes. Then I lay down in a dark room and try not to throw up and just wait it out.
I don't take meds because it happens maybe once every couple of years - thankfully.
