Usually someone who gambles then loses more money than the amount he can lose from gambling is an addicted gambler, but you can use this to not lose too much, determine the amount that can be lost and when it runs out at the limit you stop at that time, do not have other expectations when your money has been spent, if you continue to continue finances and your mental state is not good it will become an impulsive gambling, and that will make you lose even more.
More when you have experienced defeat is to go to rest and away from the mind of gambling, it will give a little peace than continuing gambling, the important point that underlies it is that you must be able to control your emotions and expectations of gambling.
When you have achieved such performance of yourself,that you can control your emotions and you can stop gambling at any time that means you have achieved a great outstanding victory for yourself.When you have gotten to such point you can do anything good with your life and quit gambling indefinitely.The problem is that very few people can manage to go there,the majority of persons are prey of their emotions and cannot stop so they don't know what to really do after they hit lost sessions in their gambling and they continue to play which is the most wrong thing one can do as lost amounts usually lead to more lost amounts and we know how it usually end.My advice for me first and to the rest of us here is to try and become the one who can fully control their emotions.
