Truer words were never spoken - you can have all the help and support in the world but you still have to want to stop.
I've struggled too with addiction but my drug of choice was heroin, which sounds awful (and it wasn't great) but the upside, if you can call it that, is that drugs exist to soften the blow.
The main thing though is occupying yourself in other ways. You'll never break the cycle of addiction if you're sat around doing nothing, because that's when it starts - "I'm bored, just one drink" or "just one smoke" or "just one hit".
You have to find something else that makes you happy. In my case it was, bizarrely, making maps for Half-Life 2. Point is it has to be something healthy that occupies you and gives you that serotonin buzz that drugs or alcohol used to give you. Whether it's creating something, doing art, playing music, whatever.
Some people fill their lives with meetings etc and make their whole identity about being a recovering addict, but i think that can be counter-productive as you're hanging around with other addicts and still thinking about your DOC all the time. You want to take yourself away from it completely really.
Good luck, you can do it.
