Thing is, in my experience, that one little pill a day becomes too much for the paranoic or schizophrenic personality. They invariably stop taking their meds because they don't like the side effects.
You want an education? Try counseling one of these people, then, after about two or three weeks, have them stop taking their meds. It's like a visit from the Twilight Zone.
Where there's worries about medication compliance, there are shots that last a week. But I doubt if this fellow is going to be out even overnight. They are probably talking about a few hours, WITH Nurse Ratchet constantly at his side.
