Boy don't I know that feeling. I have been without insurance for a few months now...and I have had insurance all my life, so this is definitely an adjustment.
I will list a few things I have tried and you may ask the doctor about some of these or do a little internet research on your own.
Anti-depressants/SSRI: Wellbutrin, Zoloft, Prozac, Lexapro, Amitriptyline (Elavil), Noritriptyline (Pamelor), Norpramin, Sinequan, Tofranil, Paxil, Effexor
Anti-Seizure: Topamax, Neurontin, Depakote
Beta Blockers: Atenolol, Metoprolol/Lopressor, Nadolol/Corgard, Propranolol/Inderal, Blocadren
Calcium Channel Blockers: Cardizem, Cardene, Procardia, Nimotop, Verapamil/Calan
Triptans: Amerge, Axert, Frova, Imitrex, Maxalt, Relpax, Zomig
Ergots: Ergotamine, DHE Dihydroergotamie, Migranal
Others: Midrin, Duradrin
Ok, well that is a list I have put together. There are literally hundreds of combinations-and they all work differently for different people. Maybe you could take this list to your doctor and see what they suggest. I always do research on meds before seeing my doc. so I have an idea of what is available and possible side effects.
