migraine
"The only medication that works for my migraines, that last typically 3 days at a time, right side of my head, in my eye, down the back of my neck and upper back. I take the 100mg tablet, 1 every 12 hours, or when I feel it coming back on. Imitrex kicks in within 20 minutes of taking it. As close to instant relief as you can get. GREAT medication."
