What keeps addicts from, successfully, stopping?

This answer is going to be different for every person. But at the end of the day, the addict/alcoholic will not want to quit when their “drug of choice” is still working (denial) for them, especially if their life still “seems” functional. Contrary to popular opinion, there is no “quick-fix,” or “cookie-cutter” approach that’s effective — i.e. a recovering mother in her forties has a different set of challenges than a college student in his twenties. That is why a recovery companion for drug addicts and alcoholics is proven to be very effective.
