She sounds like an alcoholic in denial that her drinking is really causing problems or, for that matter, that drinking in general is problematic except for a few who are just weak. Before alcoholism was diagnosed as a disease, the general view was that "drunks" lacked character and/or discipline.
She is dependent on her addiction to dubdom and doesn't know it. She will not "stop" until she is ready. Nothing you say will make any difference to her.
