This is difficult, and I know what the reasons are for getting off medication. If he can function off it then he probably wants to stay off it, but if he can't function hes going to have to come around to the idea. That's only my opinion of course, but being beaten down by illness can only go for so long I would think. Medication is a neccesary evil it seems, but it's also an absolute godsend if you find a working cocktail. I haven't been that lucky for quite some years, but I still take it because it's safer. A relapse can do irreversible damage to your brain. It's been studied, and I personally won't risk my illness progressing any further.

It's incredibly hard to just convince somebody to take these medications with the expectation of never going off... However there seems to always be hope for recovery which is admittedly quite a unique indescribable process I think. I don't know if this will help but reading recovery stories and sharing the hope that with work situations and mental stability can improve... I mean it may be a longshot but getting on the recovery bandwagon may give you the power to say, "yes I'll take the pills," but I'm going to work at healing myself which is a process that is hard to define but resources on the Internet are everywhere.
