Lucy,
Alanon is great advice. I also like calling the police next time he goes drunk mental.
The system, in America, does an evaluation on them that takes a few days.
The drunk gets thrown in a drunk tank, then gets phyciatric evaluation.
I'll call it 1st phase scared straight. Like hp said, if the drunk wants out of the mental ward they have to act right.
If he gets out and goes mental again, back he goes.
It works. The drunk can't bully the cops or the system.
I vote....Don't feel sorry, he doesn't...yet.
Thanks.
