It is better to take other options to control while doing this that you are sure will help you with for example you can use self exclude from the casinos that will not let you to play again for specific amount of time and you can't change once you self excluded but this you can change at anytime when you want and that's most likely happen with most gambling addicts who says they will stop from now but in a few days they will relapse harder and losing more.
Yes, there are many instances where a gambler gets very excited after losing and at that time he requests to self-exclude to stay away from the casino but the funny thing is that they become aggressive again for gambling within a day. In this situation, I think the decision that the gambler has to take needs to be taken very carefully. If you want to keep yourself away from gambling, then understand it well with yourself and then the next decision can be taken. Any decision should not be taken quickly during excitement.
