Different meds

I went to my facial pain doctor. He diagnosed me with chronic migrains.Just by looking at me. No blood test was taking. He told me their are so many meds for migrains.I am still taking my Tn meds with that. I am suppose to take my Nortriptyline before bed time.My days are filled with brain fog from these meds. I know these are a anti depression med. He the Dr told me I would sleep so good with this med. Wrong, My sleep pattern is so sad. I am glad I am not working or driving with this pain. As I am writing I am having strange pain in head. I know I am missed diagnosed with this. Thinking about going on grand round for help with this. Any body use that with their insurance?
