I've had daily migraines for years and tried everything I could find with the only help coming from triptons. Iv'e even been hospitalized. I finally thought what has been constant and came to the conclusion that it was my lisinopril for high blood pressure. I stopped lisinopril and started taking a back-up medicine I had and presto-within a few days my migraines are gone. something so simple and over-looked by all the specialized professionals I've seen amazing.
