I understand that you are worried about his physical health. Of course it's super important. But maybe you need to worry first about his mental state. The symptoms you describe depict somebody who is just trying too hard. He needs to understand that balance is a very important discipline to learn. Balance is everything. May I suggest some good talk or maybe even counseling?
I do understand the need to take care of his mental health, I do. And we even tried once. I hope to talk him out, and then to talk him to a specialist, who might be more convincing then I am.
