My best friend needs intervention.

Wow, that's a tough boat. She sounds like she could use some help. This is just me talking- If she's drinking heavily, she may be doing it in an effort to "escape" or drown her sorrows.
I would feel obligated if I knew a loved one was suffering and didn't help, which I can see you're trying to do. It's rough to reach out to someone. They might get angry if you confront them, and they could shut you out. It's not pleasant to have someone approach you with an intervention. Chances are she knows what she's doing it wrong, but is justifying it and really doesn't want others to know (like what if her ex finds out; will he use it against her?)
I think I'd call and let her know you are concerned and want to help if you can't reach out to her family. I think in the end, she will appreciate it. It may be a hard road for her to look at herself in the mirror right now. But she'll have to want to change; you can't do that for her. I don't know- I'm trying to speak from experience, but I may be way off base.

I would talk to her on the phone. If at all possible, you want her to be sober during the phone call.

I would tell her I want to help her but I don't know what to do. Then I would ask her what she'd do if the roles were reversed. If this "role reversal" goes as well as it often does, she will tell you the best way you can help her.
