((((((Shrekterus)))))))))))) Woah, I'd hate to be in that situation. Personally, I'd talk to your mother and convince her that he needs INPATIENT treatment, and if that doesn't work - talk to your brother himself. He's an adult, and if he's rational and realizes that he has a problem, he may be willing to seek help especially since it doesn't seem like him not getting a prescribed medication can reallllllllly be disasterous.

Just to be clear - your SIL is your brothers wife? Does she honestly want anything more to do with him, or she just wanting the money? I wonder why she wasn't the person to take him in, if he's her husband.

If all this fails - talk to your brothers therapists. I know there is "confidentiality" but it sounds like the Ts realllllllly need to be made aware of how messed up this situation is.

I'm sorry you're in this situation, as is your family. I hope you find a solution that actually helps all involved rather than just enabling bad behaviours consistently.
