migraine
"Maxalt was a wonderful medication for two years, then its effectiveness rapidly diminished.  My unforeshadowed migraines feature very mild headaches; instead, I first lost my sense of balance, then my lunch, and then the desire to live for the next three hours. Although I was on a migraine-suppressing tricyclic and metroprolol, migraines would punch through two to eight times a month. Maxalt shutdown such migraines within 20 minutes-no side effects. (NOTE: Maxalt did not suppress the rare aura).  After further adjustment of my daily medicines, my rescue medicine became Relpax   2 Aleve."
