I understand and i somewhat experience this situation and now i tend to stay away from casino because i dont have self-control. I learned to accept losses because chasing it will only lead me to more losses which will sink into me when i spent all my money.
Good to know that you know this and you have decided to quit gambling. You can develop the skills and self control and then again resume the gambling. Gambling will surely eat your money and make you sad if you do not play sensibly.
Agree too, when you are falling out of self control in Gambling, no one should advise you before you do becasue in that process gambling is eating your money and at the same time eating up your Brain. Basically, in my own case am able to control myself whenever am in action(gambling) depending whether am at lost or on the winning side, self control still the best in gambling.
