migraine
"My Migraine headache starts with what they call Aura, which is blind spots in eyesight (eyesight will be blurry when this happens) and followed by the worst headache ever. From my experience, the Excedrin Migraine doesn't work when you take it after the headache starts. But when you take it in early stage (which is for me, immediately after experiencing Aura), its very effective. Don't expect you will be relieved from pain 100 percent, but at least it helps relieving 70 percent of pain.
I would highly recommend to take it in very early stage when the migraine starts."
