what will make an alcoholic stop without any "and, if, or but"?

so, my mother, not even 40 is an alcoholic. for years, countless years, she has consumed on average 12 packs A NIGHT of beer. today i got the news that i knew i would be hearing soon, "i went to a doctor... the results came back..." basically long story short, if she stops drinking today, she lives, if not, she will die before my little sister graduates high school in 8 years. she'll be dead by 50, and that is a very generous guess, my fiancee estimates she has less then 5. the news from the doctor was end all, or die; no and, if, or but.

as far as my thoughts on detox hospitals and what not, she's gone to them in the past, makes it about a month, and starts again.

I've heard about these two drugs that make people stop drinking by force, the first one i was told about is called aversion therapy, and you take a pill once a day, and your body rejects any type of alcohol by making you throw up, i heard that is court mandated, does that mean that idea is 100% out the window? is there a way she can get it from the doctor she is going to now? i believe it is called aversion therapy, but i'm not 100% on that. the other type of drug i was told about is some type if hallucinogen that they were using in experiments (by whom i have no idea) which caused people to never want to drink or do any type of addiction at all.

i know people say someone cannot change until they want to, well my mom and i talked she knows this and i believe she truly wants to live to see her future grandchildren, and her own daughter graduate, but she thinks she cannot stop on her own. I love my mom, but she is a weak person, years of alcoholism, takes it toll on her as i said she's not even 40 years old, and she looks like she is in her 50's. you can see it in her eyes, smile, skin, hair, everything.she was also a teen mom, and yes she dropped everything and went straight to working to support her children, never partied, or anything, she over the years, all by herself, got us out of the trailer parks, into her own home, to living in a very high class area, making a 6 digit income, and living it up, but she doesn't see the good in anything she does, and feels nothing is worth it. this also sounds like she is a suicide risk too, but she' got that covered, she is taking her life the slower way, alcohol. i have NEVER in my life (I'm 20) spent a night with my mother where she wasn't drunk. she couldn't come to my high school graduation because she couldn't drink and it was too late in the night for her to wait to drink. and i will not even get into her history of getting abusive guys to her and her children that she truly said to me one day: "i take good guys, and make them into bad people". WHAT THE F*CK?

If she could just stop the drinking, EVERYTHING in her life would be better, yeah the initial detox mood swings and depression will suck, but in time it will pass.

I DO NOT want to see my mother die, so please let me know some good full crash course treatments. what i think is so great sounding about the aversion therapy is that it literally makes you not able to drink, and that's is what she needs 100% i feel!

finally, the reason i added so many little seemingly meaningless details in this is to give an idea about how she is physically, mentally, and so on. what can i do, anything? what can be done? nothing? is my little sister doomed to watch her mother die, and always ask: "why wasn't I important enough to make her stop?"

i found all this out today, i live very far away from her, because I'm away going to school, i am not around, phone calls once in a while is all we get b/c of my hard work hours, but yeah, out of the blue "so i went to the doctors last week, you know a real doctor, and the tests are back."

to name a few she's got extended kidneys, or something like that... she has absolutely no vitamin b in her entire body, and a very high cholesterol count, and by cholesterol i mean the good kind, not the heart attack inducing clogging type, which must be significant b/c she and her doctor both felt it necessary to point out... there is an abundance of other symptoms, but i have made my point.

thanks for any ideas, thoughts, stories, and information you provide, i cannot thank anyone enough who would take the time out to help, i do not want to see her die, so again, thank you!
