Mine can go like that too. Once they really get hold nothing helps and they seem to last forever. The longest one I had was 7 days. I went to the clinic twice for shots and took all the things my neuro gave me. Sometimes if I can sleep, it will break the cycle. Sometimes not. I actually lost my job in Jan 2005 because of these stupid things. That's a long drawn out story. Have you tried a high blood pressure med? I take one twice a day and it seems to be helping a bit. Maybe something like that will work for you. I can sure relate and I know others can too, seeing that we're all here.
I LOVE Imakerux quote!!!! I'll have to remember that when I'm laying on my bathroom floor with a cold washcloth on my head. That's when I really wish it was possible to cut off my head. That would feel better than the migraine.
