One of the most useful therapies is the group therapy, I think. There you can speak about your experiences with drinking and everybody understands you, because they have had the same, or nearly the same problems. Everything is better if you know, that someone else has the same life experiences. But the main results of your cure, you will get only if you want. With strong wish and strong will.
Results depend only on individual characters.
And if you go out from hospital, you should avoid every alcohol. No champagne, no beer, nothing at all. Very difficult and hard life experiences. But if survive, you'll value your life more and it will be better than ever. Every addicted person has someone or something for what is he important or for what he must be live and all right.
