I'm in a different situation because my therapist is a psychiatrist so I guess he is my pdoc and many other people's too. But he doesn't just prescribe; he does psychoanalysis so we meet frequently. He often does check his phone but it is only on silent and has only once in 5 years actually taken a call because it was an emergency. I don't mind that he check when it goes off; I think he is just trying to be responsible and he does it in a way that is not intrusive and not distracting.

Your doctor should absolutely know all your meds; that's what they are there for. And they have to keep a file that they should review to make sure. They also are MDs so they should know relevant medical information. It is not only important to making the right prescriptions, but the DSM requires that medical information be factored into making a proper diagnosis. I don't expect mine to remember everything, but if I bring something up in therapy, I don't want to tell the whole history of it all over again. Mine has a great memory and doesn't ever really screw up. But I once had one that couldn't remember my meds all that well when that was basically all he was supposed to do so I would have to spend sessions reminding him and paying good money to do so. I only put up with that for a short time, even though I liked the guy and liked the way he did therapy, but as a prescriber he just was too fuzzy to be reliable.
