I saw many people suggesting to gambler that bet huge amount and need help to stop gambling, what they suggest is limit his own bankroll and reduce the amount over period of times, this method will not work seriously. Because of human mentality, casino win on human mentality vs players. Reason is when player win, they feel money is so easy to get and they want to win more, and when they start to lose, they start to bet more and want to recover back their losses.
I will explain below:
once you deposit and loses money, you will have the mentality to deposit more and think of recovering your losses, at this point of time, you already don't want to win profit anymore. you target is just to recover your losses, and you tell yourself too when if I recover all my losses back, I will stop.
But at this point of time, you start to lose more and more, the more you deposit, the more you lose. At this point, devil already control you, you will see nothing beside anger and desperation.
Just ask yourself honestly, how many times have you met with the scenario I describe above, I cannot change human mind, every person have their own thinking, but I wish if anyone read my post, go think of it calmly and if you get what I mean, just quit gambling for good, life is not all about gambling, stop sitting in front of the PC and thinking money will drop from the sky. There is no free lunch in the world, get a stable job, lead a normal and happy life, enjoying good food or even holiday with your hard earn money is even better.
To quit gambling for good is don't deposit even $1 at all, just play with free faucet for fun and and find something else to do other than gambling. Maybe meet up your friends for dinner or movies or playing PC games is another good way.
If you're addicted then this is usually the only way. It's most likely easier to stay away from depositing in the first place than it is to set limits and gamble 'a little bit'.
You'll only end up fooling yourself and you won't be able to control your behaviour.
