I'd be concerned mulranna that she isn't seeking this information herself; because that probably indicates that she isn't really ready to stop. Be prepared to put all the information her way and for nothing to change. It's easy to get over-involved and think that the problem is simply about a lack of information, but the truth is that this information is very easily found - if she wants to hear it.
I stopped drinking midway through divorce (which annoyingly still isn't finalised!) from an abusive man, and I would say my drinking (which wasn't as extreme as your friend's) was symptomatic not only of the relationship itself, but my life as a whole which of course led me to be in that relationship in the first place. I don't have the answers for your friend, but the problem is likely to be highly complex and personal. This is why I think it's so important to seek the information herself. So many people I know started off by reading the stories of other similar women, and starting to get recognition that there were thousands of women out there just like me who not only had stopped drinking, but whose lives had flourished. That she believes AA is the only real option available to her indicates to me that she hasn't done any reading up about it herself because that's very far from the case.
I'm sorry to appear negative about your attempts to help, I don't mean to be - I think you should put as much information her way as you can, but then be prepared for the drive to stop to need to come entirely from her. There needs to be something of an 'awakening' and it's got nothing to do with knowing facts.
Helpful starting points:
Soberistas - A great site for daily blogging/checking in
Books such as "Mrs D Is Going Without" (Lotta Dann); "Calling Time on Wine O'Clock" (Lucy Rocca); "Sober is the new Black" (Rachel Black); "Why You Drink And How To Stop" (Veronica Valli) are all good reading material.
The Bubble Hour podcast is also excellent.
I agree with glad that she may well have been lying to you and others about her drinking and that she needs to be able to have an honest conversation with a doctor about the extent of it. Good luck!
