When and how often do you have migraines?

@Courtney_J Mine are cyclical, following my period. I get them in the last few days before my period or in the first few days of having it. When I'm lucky and they fall on the weekend I usually take some medicine and lie in a dark room and try to sleep them off, but if it's during the week when I work I take my box of anadin extra with me to work and avoid people as much as possible. I used to wear sunglasses against the light, but my new glasses have a blue-light film on them and that has helped a bit. 

@Raindrops I luckily don't have them every month, but I'll get one that last at least a week every six months or so. I usually take a shower with the water on blast beating down on my head and neck and it almost feels like a massage and then I try to sleep it off. I usually have to shut out all light and put a pillow over my heat so it's pitch black, otherwise the nausea will overwhelm me and I have to run to the toilet to be sick. I've heard blue light glasses can help with headaches so maybe they'd help my migraines too
