migraine
"When I was about 23, I started getting horrific migraines out of nowhere that would incapacitate me for days at a time. My neurologist couldn't find anything wrong and I tried several medications (some would take at least 12 hours to have an effect). The only medication that ever successfully treated my migraines was Maxalt and it pretty much gave me my life back. It would still take at least an hour to work but it was really a life changer. Ultimately, I sought an ENT and after I had sinus surgery (and corrected my deviated septum) in 2011, my migraines never returned. But if they ever did come back, I would be running to Maxalt as my savior again!"
