When I hear a recovering addict say, "I am staying clean and sober for myself," I know that person has the right attitude. That person is not doing it for anyone else. That person is not trying to make someone else happy. That person knows that he or she doesn't want to continue to suffer from addiction. That person knows he or she has a problem and is not merely trying to get someone else off his or her back.
Write down on the left side of a piece of paper events that have caused you trouble. On the right side across from each event, write "yes" if alcohol or some other drug or addiction was related to the troublesome event. If you tend to see "drink = trouble", you need to stay sober for yourself. The happy consequence is that others will seriously appreciate your sobriety too.
