I would say that your treatment worked and did what it's supposed to do, freeing you from your addiction. I think it's perfectly acceptable and healthy to move on from meetings and carry on living your life as a non-drinker or drug user. I don't believe in the disease model of AA so I don't believe that it has to be a life sentence. People quit drugs and drinking all the time and go on to live normal balanced lives. I read some stats that said 75% of people will beat their addictions with or without treatment. My opinion is that if you feel solid in your recovery and don't feel like meetings are necessary for you anymore then you should trust yourself. You can always go back if that changes.
