FYI, here in the UK, it is becoming acceptable in court proceedings where alcoholism is alleged and children are involved, to ask for a hair alcohol test (similar to a hair strand drug test, google). I don't know if that is permissable in your state? Again, a lawyer will be able to let you know. I find I am always more calm if I know the facts of what will/will not help in a particular situation, and legal things are often counter-intuitive.
