I've been on numerous medications and as soon as I start them within a few months after being on them they stop working. Currently, I'm on Nurtec 75mg, been on it going on three (I think) years, its stopped working been trying to go on something else but my state insurance is being difficult on what else I can go on, my neurologist had said we might be at the end of the rope of finding something else to go on because of the issue with my insurance. What else can I do? I'm always hydrated I've cut a lot of things out of my diet. Please help!
