The first rule of recovery is that you must change your life. What do you need to change? If you understood the previous paragraph, then you need to change the way you relieve tension. Everyone needs to escape, relax, and reward themselves. Those are essential coping skills for a happy life. But addicts don't know how to do those things without using.
If you manage to stop using for a while, but don't learn how to relax, your tension will build until you'll have to relapse just to escape again. Tension and the inability to relax are the most common causes of relapse.
