Opiates generally do not help
migraines. Some people are triggered by caffeine,
for some people it dialates blood vessels and helps. Some people get rebound headaches.
My triggers are opiates, baclofen, Xanex, most sinus medication ( benadryl, claratin, allegra, etc.), extreme cold or hot weather, neck tightness from MS.
I take Immitrex, have tried Topamax and lots of other drugs. They mentioned Botax injections to me last week.
