Is it harder to control gambling or limit it without falling into excess than to stop gambling forever?
This is the good initiative when a person wants to completely stay away from gambling. A common reason is that they may not be able to control themselves. They know that if they somehow get into gambling again, they can end up in big losses again. That is why taking precautions beforehand will be a good decision for them. If a gambler can stay away themselves from gambling, it should be easier for them to exercise self-control. It is entirely depend on gambler's personal view what they feel is best.
This is usually the feeling a gambler gets when they disregard the rules and lose excessively. But if they had been able to manage their gambling in a controlled manner from the beginning, there would have been no need to take such a decision.
I think addicted players just periodically have a desire to play more or place higher bets to feel the game and strong emotions under adrenaline. Of course, somewhere in their heads they understand that it is necessary to control themselves and act according to the rules of bankroll management, but that click that happens at some point spoils everything. Probably some wild boredom and routine makes them do this, maybe a boring life in which it is incredibly boring to live. I think these reasons are the most common problems for these players.
