Wanttobe,
I too am glad you are here. You say he won't drink and drive after two DUI's? Well that proves he has some sense and some respect for the law. Good for him on that one.
It sounds like it is the rages that most concern you. Why not call the police? If he gets violent after, call them again and again. I love my husband dearly (he drinks daily) but that is something I simply would not tolerate. If his basic common sense has kept him from driving while drunk, who knows, the fear of legal intervention might keep him from raging while drunk too.
I had to call the police on my own son and all they did was make him leave for a cooling off period. They didn't put him in jail..but you never know.
Action speaks a whole lot louder than words.
