migraine

I have suffered w/migraines for 49 yrs. and still suffer about once a wk. or more. At the present I am taking Percocet.Most of the time I take Excedrin Migraine because the Doctors in the clinic in my town do not prescribe narcotics for pain management and my primary Doctor who was in the same practice is retired. He used to give me Demerol w/phenergan injections if I had been suffering for 3 or more days. Does anyone have any suggestions for things I can do to get relief? I have a neurologist and that is who gave me Demerol tablets. A lot of the preventives I have tried effect my eye pressure and because I have glaucoma I can't take them. Most everything that has come out my Doctor and I have tried with some success for awhile but after all these yrs. we are running out of any possible trials other than trying to deal with the pain.  Thanks for letting me vent.
