if he does get behind the wheel drunk - call the police.
his hiding the problem (and your own role in keeping it hidden) will stand in the way of his ever recovering.
losing his job pales in comparison to killing your children or others, doesn't it?
Is his job worth risking your lives?
Is his job worth living like this?
Meantime - you might consider leaving to protect yourself and the children.
Being a part of his cover-up and his madness isn't helping....
I'm sorry you find yourself in this position.
