Yes. That what was the problem.

I had my pdoc give me Primidone in place of Propranolol. It work reasonably well. I asked my neurologist about Primidone, and he babbled a bit meaninglessly at me. He could not really tell me why he told me Propranolol was my only option, the one that would work for me, and instead not place me on something different when Propranolol was not working.
