Question about episode 8

How long did Billy and Rod have to wait for the doctor when Daisy ODed? Because Rod calls some Doctor Jacoby on Trinity Road about a “toothache”, which clearly means that he has contacts planned out for this kind of stuff. But, assuming he doesn’t have the contact of a doctor specialized in drug abuse for every single city that they go to, at least I don’t think he’d have at that time, how far away is that Doctor from the hotel that they were staying in? Like was that Doctor even in Miami? Where is this Trinity Road (I'm not from the USA)?

Poor Billy. He probably spent the scariest hour (hours???) of his life holding Daisy in the shower feeling completely helpless just waiting for that doctor and praying that she won't stop breathing out of a sudden.
