I hope and pray that it works out good for you and for her.
I went through one of those processes w/ my brother after he tried to kill me and himself in my living room -- where I had taken him in because he was homeless.
He never did manage to get sober and stay sober and died about 18 months after getting out of the hospital -- that I had became a part of the "commitment process." He never forgave me for it and raged on me after it. He was able to con the docs into letting him go three days after he had been committed convincing them that "I had done this mean thing to him".
I certainly hope that your experience & your mothers experience turns out much more positive than mine or his.
Afterwards -- I had to learn to take his rants & ravings up until he died. I don't want to cast any shadows of doubt for you -- and, if my experience shares anything for you -- I hope that it is: Don't blame yourself if the results do not turn out favorable. And, don't take it personally. You're trying to do whatever you can do to save your mother's life. And, she may not appreciate it. Us alcoholics get really sick spiritually. Our love for our family is deep -- but, often, we get so sick, that we are unable to show it.
You're in my heart & prayers.
I would highly suggest that you contact Al-Anon, which is kind of like a "sister program & Fellowship" to AA. They exist to help the non-alcoholic families -- that suffer as a result of "our" alcoholism. They may be a tremendous support for you!
