I just have to comment on one thing you said:

That's an AWFUL lot of responsibility to put on a 15-year old. Talk to her if you want; tell her your plans, tell her you want to be a better mom - a SOBER mom. But don't make her hold you accountable. Because then what happens if you slip and drink again? She's going to think it's her fault that she couldn't stop you. She won't understand.
No, please. Use us if you want accountability. Let your daughter be part of your plan, but please don't make her be your parole officer, so to speak.
I hope that didn't sound harsh - I didn't mean it to.
