Anyone else have ideas for these migraines?

They are getting pretty bad with me... I have an ongoing headache from the facial RSD. My Dr tried imitrex with me and it was working, but stopped. I cannot get rid of the headache totally. It has been up and down... It gets so bad that I get really really nauseas, vomiting, dizzy, double vision, and faint (I fainted once this past week).

Right now I am taking some pain meds until I get in to see a neurologist, and they help somewhat and I can do things (but once it wears off I'll be in even more pain). These headaches are TERRIBLE and I need some relief!! Ideas are greatly needed.
