I don't understand why someone who has quit will ever go back to gambling. It's like other vices, if you quit smoking, then good, no reason to go back to it. And it just will add another pain in your life if you have quit then go back for some reasons only known to you.

Just be resilient and find out the demons that once conquered you. Man enough and don't like others or the environment around you influence your life. If you are stress in your life then go and exercise. If you have under been peer pressure then move out. If you frequently see casinos, then go and move on a different route.
