What I observe in myself is only the temptation to continue playing after losing gambling budget. That is, the temptation to chase losses, even though I know I shouldn't. It's just that it's too hard to accept the fact you have lost and you will end your gambling session with less money on your pockets than when you firstly started. Anyway, I don't let that emotion grow inside me, so I immediately stop playing once my budget is gone and try to think on another activities until I calm down.

Self-knowledge is a very important trait to avoid feeding a potential addiction into becoming reality. Develop it progressively inside yourself, and you will be more likely not getting into trouble in your daily life. And that is something which is useful besides gambling matters, as the impact will be positive over every aspects of your existence.
