From what you've described, I would go to Doc B for the refill and try to get in to Doc A in the meantime to see if you like him/her better. If so, then switch; worse case stay with B. I can't see going back to the GP at this point only unless had access to no doc at all. I don't know if this helps or not. But I am a firm believer in finding the right doc for you that you are comfortable w/ but making sure you are not w/o care in the meantime. Good Luck!
