All I know after reading and learning about this disease, is that only the A can get himself/herself the help. We can't love them sober or make them get recovery. I read the book Under the Influence and Beyond the Influence which helped me know what was happening. There is also some good information about trying to get the loved one help, though I feel like the advice is mute as only the A can decide he/she has a problem and get help. Thousands and tens of thousands can be thrown into rehab facilities but many times the A relapses because he/she doesn't want to quit drinking. I know it is never too late to get help if the A wants it, and wants to live sober.
I think the best advice I could give is to get into Al-Anon and keep coming back here. Those two things have helped me.
