Hi Val. Give her time. This will pass. In my case I was no more angry without drink than I was with it. But - it did take me a while to learn how to deal with the terrible feelings that booze helped me to deal with. My husband just let me "be" in those early months. I always knew that he was there for me, not to shout at, not to rant at - there were always very firm boundaries.
Good luck to you Val and to your wife.
