I have been a migraine sufferer for over 30 years. I started when I was in elementary school. I have tried them all. The most effective one for me has been verapmil. The others did not work. I have had a 90% reduction in aura and other symptons as well. It took me several years to find someone who knew how to treat migraine. I had aura, dizziness, nausea, and would even pass out at times.
