Sure, this makes sense but so sad. Addiction of course can be said to be like the Bible story you narrated, one would quit for some time, yet failure to occupy the space with much healthier activity, the desire comes back even stronger than before. Stress, being alone, or even being around those gambling may be the reason for such pull back in. The moment there is a relapse, addiction may get deeper than earlier. This is the reason why to recover you need more thank just quitting; there is a demand for developing new habits, better support systems and of course purpose to avoid the return of "demons".
