migraine
"This is a MIRACLE medicine for me and is most effective when taken at the onset of a migraine. Within 20 minutes, I can feel the relief setting in. Within an hour, I have no sign of a headache or the usual symptoms of vomiting, blurred vision, ringing in the ears, etc. If I 'deny' that I feel a migraine coming on and take the pill after the headache has progressed, it takes a little longer for the pill to work.  Before this medicine, I had become a prisoner in my own life, not daring to venture far from home. THANK YOU Imitrex for giving me back my life!"
