I've pretty much decided that all my doctors will be in the same clinic system, shared charts and a pharmacist downstairs ready to throw a hissy fit for an interaction of some sort.

Dentists I think are the worst because they want to rely on short term pain management with opioids (bad news #1), and often think steroids are a universal fixer upper (bad news #2). While also being least aware of interactions with non-dental related medications.
