I somehow missed this post until just now when I was wondering how you were getting on WAWF.
Alcohol is such a dodgy issue for women and I suspect that it's a bigger problem than most people understand. I think I've said to you before that I'm not adverse to a tipple myself and I know that my drinking during the past 12 months of our marriage contributed signficantly to my problems and especially my depression.
The problem with alcohol though is, despite the inspiring story you heard from your colleague, it is very difficult to get someone to stop drinking, or limit their drinking, until they are ready to do it themselves. I can guarantee you that if you go to her and suggest she needs help with a drinking problem she will resent it and it will give her one more excuse for walking away (that old husband of mine was so disrespectful he accused me of being an alcoholic ...) you don't want that.
How are you anyway. Thinking of you.
