I doubt that you can stop gambling when you are addicted since it’s very hard to notice the symptoms due to the addictive nature of gambling. The only way for a compulsive gambler to stop is if someone help him to change or he doesn’t have any money to gamble.
I think to come out of addiction is based on certain circumstances which I agree that if someone doesn't have money to gamble again then that can force him to reduce playing and probably stop totally. But if you try to stop the person where he is still having money to play, the person will still look for ways to play because he already have passion for playing. Gambling addiction is like a passion and only very few things can stop someone out from there passion like if the person is physically not dispose to it anymore.
I agree with you and this passion grows bigger and bigger with the passing of time,it is different from other passions which after 1-2 years they start to fade away from the level that you had for them in the beginning and this is a big problem.If the person is run by his passions and not him running the passions this is much more emphasized in the gambler which can really fall prey to addiction very easily.In order to stop having not money is not enough as he will stop only temporarily while to quit for good you need professional help and a strong inner desire to quit,there is no other remedy to this.
