Migraines are the absolute worst. On average I would get 6-8 a year. My triggers are primarily not eating frequently enough, bright lights and constant loud sounds. Knowing that, I mostly am able to avoid them and I can usually tell early enough when one is coming on to course correct. I never really explored any medication with my doctor because it was infrequent enough that I didn't really think of it. Then I had the worst migraine of my life. Typically I would vomit some as it starts to get really bad. Usually at that time I'm already laying on the bathroom floor because there are no lights of any kind in my bathroom that aren't tied to the switch. Also I rapidly alternate between being freezing cold and burning up so the cold floor is ideal (I also bring a blanket.) If it has hit this point I'm often in there for 4-6 hours before I can at least move to the bedroom.
The worst one, however, I spent 8 hours in the bathroom and for that entire 8 hours I never stopped vomiting. Well, I did, but only because there was nothing left inside of me. Dry heaving for that amount of time is not fun and it is even worse when combined with the terrible pain of the migraine. I never want to have that happen again. I genuinely don't know how people who get Migraines once a week or even more often can do it. If I got migraines like that every few days I would have blown my brains out a long time ago.
I try to avoid my triggers as best as possible but I was also prescribed sumatriptan as a last resort to take if I know it is going to hit. It has its own side effects that suck but it sucks a lot less than the migraine it prevents.
