Not sure if I'm allowed to recommend a book on this forum but here' goes since you asked.
I found a great book which is like an interview of around 250 people who have stopped drinking for 5 years or more. It goes into summary about how they did it (many different ways) with or without the help of AA (half did with, half without)
It's a great book just to get feedback about how people felt at certain situations and how they overcame difficulties. Some found reading, some exercise, some AA meetings to get through the hard times.
It's called "Sober for Good" by Anne M. Fletcher and I thoroughly recommend it. I've read many recovery books and this is my favorite so far.
Good luck by the way, it seems like you know in yourself something has to be done now which is a great attitude.
