Don't guide her, unless she ASKS you some form of "What do I need to do?" or "Tell me what I need to do." And even then, at THIS early stage (the one Greek refers to that her husband did), I like the response of "This is your mess; you get to clean it up."
Let HER tell YOU what she's willing to do to clean up her mess!!
Again, be prepared for incrementalism (which WON'T work), and some pullback from her position of last night. The alcoholic usually swears that "I will drink less," long before they hit bottom and give it up altogether.
