Hi there and welcome,
My name is Rose and I am an alcoholic.
My experience is that she is hiding her drinking so that it appears to you she isn't drinking as much.
I hid my drinking so my DH wouldn't know that I had a bottle of wine before I had the glass or two with dinner. Then, I blamed my passing out, I mean falling asleep on my sinus medication, the herbs I was taking, etc. rather then being hones about my drinking.
I could be wrong...just sharing my experience with you
