Help beside migraines?

What are some meds that I can try to manage my migraines? I be on Topamax for a period of time, but afterwards it stopped working. I was on Depakote also, but it made me consistency sick. I'm willing to try anything almost.
I receive Ketoralac injections when needed and sometimes take Perocet. But neither help 100% of the time.
Is there anything that you would know in the order of that could help me?
Thank you. I don't know any prescription meds that'll minister to, but with over-the-counter meds, I transport Aleve. Not sure if that'll work for you. Did you get a CAT scan by your doctor to see what's the actual problem?
Magnesium help.
