Non-Opiate Acute migraine treatments

After 25 years of migraines, using every med with anecdotal efficacy in prevention under the sun (namenda being the most recent), I still have migraines. Barometric pressure, floral scents... we could spend all day on my triggers. So, I ended up with a dependence on opiates that were prescribed for my migraines. Seizures from the meperidine metabolites were enough to get me into detox a year ago. Now I find myself with no solution but to suffer, throw up, and hide in the dark until I can't stand it any more and end up in the ER for fluids, opiates (tolerance is still huge), and anti-emetics. It's an endless cycle that me (and my family) are sick of. My ex-husband has decided that I'm really putting myself through the *miserable* ER for a "fix"- even when it's done with my addictionologists treatment protocol, and not at the bioequivalent of my oral doasage. I have no quality of life. Drugs like midrin, fiornal, and toradol don't help, nor have any of the triptans. Trying to make more lifestyle changes (adequate sleep, hydration, absinence from alcholol or caffeine) but the headaches still happen. Is there any choice but opiates?
