"I've tried a few triptans but this is the first one I've tolerated.  In general, it is effective within an hour.  However, in the rare case my migraine is preceded by an aura, it seems less effective.  That said, since I can't tolerate other triptans due to side effects, I like this one best.  (My insurance company doesn't like it and I needed to obtain prior authorization, always a headache!) Use the coupon for the copay if you can."
