You never stop,you play while you have money it is addictive as a drug when you have you use,when not you try to find her,in gambling when you lose money you find way to find money when you lose everything you will stop.
That's because you do not have the discipline and you do not want to accept that loses, actually when gambling and we have a bad losing streak and we are down big we like to make promises that we will not gamble anymore but that was only in our mind because our heart will tell that we should still gamble to win back our loses. Even if how good your mind is but you cannot control your emotion, I guess it would be easy for us to get addicted.
