You know, before the firestorm comes you could always just try a nice little chat.
"You will never drink and drive with our daughter in the car again, because I will castrate you if you do. No drunk thinks they have a probelm until they get a wake up call, and I am not going to allow your wake-up call to be something horrible happening to our daughter at your hands. And before you go and justify this or blow this off, F you, for letting your weakness overcome the want to protect our daughter. Every addict has an excuse."
Of course...
That might be a whole different firestorm.
