Is he on meds for his mind now? I know, they can be crappy, but when it keeps you from psychosis it's sorta important. Although the psychosis can come back when your on meds. Is he in psychosis now? If he is, I'd make him take meds even if he refused. Its the sensible thing to do. Otherwise he can do very stupid things, that are much worst than being on crappy meds. Like somehow he can get the idea to kill himself (thinking he's supposed to) and stuff like that. So, if I were you, I'd make him take meds. Or make him go to a hospital. If you think that's warranted. Good luck
