Rainbow, that really is a shame that your mom went against his wishes. I do think she might've been afraid of having him at home in that condition. I understand your anger and frustration. I do think you should try to see him one more time if you can.
Rainbow, a NH sounds like a good solution. I hope he makes it there. Please keep us updated.
That is great news, Rainbow! Hopefully, he will be discharged with some medications such as Lactulose.
