{{{Teppy}}} I'm so sorry, that's such a difficult position to be in. Do you think he is even taking the medicine that was helping him in the hospital even at the lower dose?
I think he probably is, but my brother thinks it's not close to being a therapeutic dose for him.
Any chance you can convince him to move to an assisted living situation?
That's going to be a really hard sell. But there are services that can help him in his home, and he might be more likely to agree to those.
