I spent about a month a couple years ago having migraines, which I had never had before and inexplicably stopped having afterwards. I was prescribed a generic version of Fiorecet; you don't mention it or its unusual ingredient (butalbital; it also contains caffeine and acetaminophen). This worked almost completely if I managed to take the pill during my prodomal symptoms (weird visual aura, in my case; I don't know if you get this warning). However, even unmedicated my headaches did not last as long as it sounds like yours do. Apparently Fiorecet isn't customary for migraines, so you may not have tried it.

I also pestered my significant others for neck massages. I do this anyway but it was especially important when I had just had a migraine.
