Have had migraines for several years. Used to take preventative & acute attack meds. Preventative meds were Topamax & Depakote. Also used to take Imitrex, but take Treximet now & it works even better. About 7 years ago, I had a migraine that lasted the ENTIRE summer....got a little better & worse but it never went away for months. THey admitted me to hospital & gave me i.v. meds that made me really sick.
