Yes, I agree with you, but not playing after losing is not easy for everyone. Many simply cannot sleep peacefully after this, thoughts creep into their heads, the player becomes as if not like himself, he just wants to win back. These are signs of lack of awareness, immaturity in the game, such players are better off staying away from gambling altogether. Because they cannot do something very important, take a responsible approach to business, even if it is a game. After all, if you do not know how to stop, you can fall so deep that it will be almost impossible to get out...
In that you are completely right, when we go to sleep sometimes we recreate everything we lived during the day, and when we focus on the game it can be that it gives us that anxiety, and that is something that is very difficult to get rid of, although I believe that the best way to get rid of these symptoms is by holding on to our discipline and above all to acceptance, I see no other way, if we pay attention to those pansimaiotos, not sleeping, we will not connect to go play and we will lose more, it is healthier to try to think about something else, do something or establish a strategy to be able to sleep , I recently read that for those who cannot sleep it helps to blink a lot, for 1 minute, that it produces sleep.
Accept and move forward, that will help you a lot in terms of thinking about what happened after you play or after you gamble, like what you mentioned discipline is very important, if you have and you continually practice that same type of discipline you'll not going to lose your way and every decision that you'll make will help you to prevent losing what you can't afford to lose, as from that moment,
your eagerness to keep playing will be develop if you don't have the right attitude and discipline when accepting your loses, unlike with those who can control their emotion they are capable to let go and move forward whatever the outcome after they place their bets, win or lose they'll stick with the set limitations.
