Trying the liberary is a good start, but also you can go to the dr, and discuss your concerns with him , with your wife. As you said, you are in this together, the rages afect your household. I hope things work out, this is just another part of the jounery, and the good news is, it gets a lot better! You can also see a therapist with your wife.
Thanks for the suggestions. It is very painful for us as a family. I know it must be for her. I always thought this period of life was an "old man's tale" along with PMS. This is serious stuff and a major learning experience in humbleness and understanding a a man.
