Having some limits and following them up can make wonders in that regard. It's hard, but it's worth it.
I think that in a casino the only thing we have to limit ourselves is money, because emotions and impulses, despite how much we try to limit or control them, at the end of the day we end up giving in and that's not bad, it's just not advisable, for me it can be a very bad way not to express our emotions, our impulses, it's a game, but yes, doing it with limited money, because if we don't have control over our money, then it will all go away, and without money it is something that I do not recommend being.
Once we can enjoy playing gambling using limitation, we will see that gambling is just an entertainment that can makes us feels relax
It can be hard to relax when the consequences of entertainment are losses. 
On the contrary, at such moments tension arises, not relaxation.without trying to achieve anything from gambling.
Doesn't it sound too doomed? Many gamblers still hope to improve their financial situation thanks to gambling.
