Not all migraine sufferers are the same. I have suffered from fairly regular migraine headaches for about twenty years (can't believe it's been that long!) and sometimes taking something like 200mg of ibuprofen when you first feel it can result in the progress of the headache being 'arrested' at that stage and though it still lasts as long as a normal headache before it passes, sometimes it manages to stop it from fully blooming.
However, even within my own experience, only ~1/4 of my headaches respond this way. I've taken other medications as well, and the majority of my migraines don't respond to anything other than trying to soothe the symptoms :/ In the majority of cases ~3/4 of the time, there's nothing you can do to stop it, you just have to dig yourself in and get to a quiet dark place for a few hours until it passes.
