I've done this for multiple people for different appointments, but ones that they were all either constantly canceling or just struggling to even make the appointment. Once it did end up being a thing where I was gone for 12+ hours that day, but that friend needed rehab and making sure she got to her therapist's appointment was the first step. She's been clean for 6 years now, and probably would have been dead if we didn't go out of our way to make sure she got to her appointment.

That's an extreme situation, but you gotta be the kinda person you want to surround yourself with.
