migraine prevention
"I was prescribed this medication for borderline hypertension 140/90.  I have also had migraines with aura for years.  I have tried many medicines.  For the first 3 days, I had a headache.  After that, bam, no more migraines with auras and very few headaches.  It is incredible.  I take 2.5 mg per day.  I finally have my life back!"
