I think people need to find a way that works for them. I know that I do need some kind of program, but that is just me. Some people don't and they are able to stay sober. We are all unique in our own ways and what works for one person, might not work for another.
I think the most important thing is to realize that you do have a problem and that you do need to change the way you think and do things. And to recognize when something isn't working for you.
Everyone has to find their own path. and the journey we all take is personal for each of us. If it keeps you sober, that really is all that matters and is okay in my opinion.
