Sumatriptan
"The first time I used the Dosepro, I was leary.  Within 10 minutes I was not only relieved of my migraine, but it was the most clear headed I felt in forever.  The second dose I took, I was not near my medicine and I had a full blown migraine, so it wasn't as good but a very close second.  I love this.  Freedom to make plans and not have to worry about cancelling due to migraine. Yeah!"
