Most doctors I've spoken to have been quite happy to work with me rather than against me.
The unfortunate trick is you need to self educate to speak a bit more in their language. You also need to accept they are often working within rules that are unintuitive.
E.g. I prefer a particular brand drug Vs the generics. (The delivery method was slightly different) I had to cycle through the generics so they could tick them off in the system. Otherwise it would try to automatically shift me to a generic.
