You are right, I do believe that anyone that can not have self control over their gambling habits, then the person should not be gambling, because they will definitely encounter big problem as a consequence of their addiction. It would have been more better that they quit than to face such big problem. I know that there are some people that when they realize that they can not practice such self discipline, they will just stop but some people would not.
Gambling winnings are only yours when you walk away from the casino at the point of winning and do not play again for a while before returning back, this is very important because if you continue to gamble after your initial winning, you will still lose that money along the line, so let it be that after each game winning the next thing is to take a bow to walk away for that main time to return when the time is right for you, and to effectively achieve that determining target you will need to set a target and stoppage time for yourself, this is very important in other to stay safe from getting carried away to overdo things that can lead you into worst conditions.
