I can understand; as gamblers, we get tempted to place bets. The best way to counter this is to set a profit limit or target. Once the target is achieved, make the withdrawal. If you keep your balance in the casino, then you will eventually get the temptation to place a bet and will continuously want to make more money. Hence the best thing is to just withdraw the funds after a certain amount is made in profits. Withdraw the initial amount you used, and if you really want, then gamble with the previous game’s profits.
You should know that an addicted gambler does not have any specific time frame or profit target for gambling bets. Because when they win repeatedly he will bet again and when he loses repeatedly he will bet again to get his money back. Generally the gambler will not rest until his funds are exhausted. So once addicted to something, it is not easy to give up. However you may be able to reduce your gambling if you devote yourself to other activitie.
