Oh yes.. the fury... I know it well!
I believe anger is a form of self preservation. It's more comfortable to be angry then it is to feel all the pain.
We've all been so battered by the disease of alcoholism and most of us have been codependent to one degree or another. I think it's completely normal to feel angry at the drinkers. It was definitely part of my process. It motivated me... it kept me protecting myself until I was feeling safe enough to let my own demons out and then kill them off one by one. It was not a comfortable process. It hurt like hell, but it was what had to happen so the healing could take place.
I've seen great growth in you since you got here Wamama. I think you are headed in the right direction. If I had to guess, I would say the anger you are feeling is a stage that you will manage to work through.
