Alcoholism is a disease of the mind, body, spirit and emotions...how qualified are we to handle that?  I was born and raised in the disease of alcoholism and married into addiction and had so many relationships (affairs) with alcoholic/addict women I pale at the thought...additionally I also stopped my own drinking 35 years ago and the only people who have been helped by that are those who came into Al-Anon and then AA for the same reasons I did because we were affected deeply from it.  Alcoholism touches and affects everyone it comes into contact with family, friends, associates and it is incurable...it can only be arrested by total abstinence...if not the alcoholic has but three choices...sobriety, insanity and/or death.  Your sister is trying to quit on her own and then what works best to do it with the help of those who know how to get and stay sober and most of them are in AA...still without guarantees.  For those of us who want to be of support we can  also go learn from others who have learned from others how to do that also.  Welcome to MIP and the Al-Anon Family Groups.   MIP has this 24/7 board and cybermeetings twice a day.   Al-Anon hotline in your area can be found in the white pages of your local telephone book where you can learn where and when we get together in face to face meetings on a weekly basis and also get in touch with the literature that is available to us and others who are willing to guide us on this journey on how to be supportive of a loved one with a life threatening disease without attempting to fix them.  None of us here honestly know how to fix an alcoholic or addict...we have tried almost everything almost all the time and it didn't work.  Prayers for you and your sister...I hope she reaches out for help from those who know how to do it.   Keep coming back (((((hugs)))))
