Having some limits and following them up can make wonders in that regard. It's hard, but it's worth it.
Edit.
I think that in a casino the only thing we have to limit ourselves is money, because no matter how much we try to limit or control emotions and impulses, at the end of the day we end up giving in and that is not bad, it is simply not advisable. For me it can be a very bad way of not expressing our emotions and our impulses, It is a game but we have to deal with limited money , because if we do not have control over our money, everything can be spent and without money it is Something that I do not recommend being.
Yes, that right, the only way is to limit the use of money from each gambling session that we do and that way we will definitely be able to control everything more easily to minimize the occurrence of some bad things that might be quite disappointing.
It just that on the other hand gambling will always provide victory over the amount of money that has been lost, this will be the same as detrimental turn but some people are unable to think this far because they feel they have been lucky to win.
In the end, the amount of winnings will never be equal to the amount of defeat, financial limits can reduce the level of increasing losses but in determining things like this only responsible people can do it, most gamblers still often fail and are lulled.
