Jeremy, Indianapolis, IN - 06/07/2011

feel like this medicine was a miracle. I was prescribed it today and the first dose did not work as I had anticipated though I was already 2 hours into the migraine. Tonight I started to get another and used it right away. It made my symptoms go away in about 5 minutes. Truly amazing. So much relief.

I couldn't even stand up. I had a horrible reaction. I didn't think it was possible to get worse but I got sick to my stomach, had a hard time breathing and it actually made my migrane worse.
