Your post makes me tired all over again. My son is 28....
You cannot do anything to get her sober...she has to that on her own. Long term programs ARE better than short term...they are dry longer and there is more intensive input over a longer period of time. Half-way houses after treatment are also effective. The alcoholic is living in a sober environment with restrictions while they get a job, work, attend meetings and put a life together.
Your daughter seems to be looking for a quick fix...ther isn't one.
In the mean time make yourself at home, get a copy of Melody Beatties "Codependent No More" and take care of yourself.
Hugs,
