20+ years of migraine pain. Trying to find what works for me as a preventative aid. Have tried propranolol, amitriptyline. Neither worked. Now I'm on gabapentin 300mg once daily. It's not doing a thing. For those that have tried it, we're higher doses the key? I plan om discussing the increase with my Dr but feeling discouraged that I may be striking put here. I've considered botox but have read they can make them worse particularly if you have bad neck tension.
