Try to identify the emotion that triggers a cigarette craving. For me it was a spirit of rejection. Jesus freak that I am, I cast the spirit of rejection out in the name of Jesus and loosed a spirit of peace and wholeness. If one isn't into such, one could use an affirmation like "I'm done with that feeling of _______ and I am going to entertain a positive feeling of ______ instead. When we give something up, don't leave the space empty. Fill it with something good. The cigarette craving will pass.
