Thank heaven, I've never been dismissed by a Neuro, to my knowledge. They look at me funny about the LDN, but I just look funny right back at em..
Other than being honest, I don't know how to handle a Doc's skepticism.

Like Dej said, if he's of that mind, it doesn't matter. I will pray that he/she is open minded, knowledgable and compassionate.
Good luck..
