Distracting yourself with other things will be the best approach when it comes to this so that you will be able to make yourself that getting distracted on playing gambling because on the moment that you do find yourself having those kind of aims and thinking about doing gambling then you will really be just that eventually keeps on playing or going back into it. Also, if you do really mean out on quitting or stopping gambling then you can really just that stop midway. Somehow it wont really be that so simple on this case when it comes into this aspect specially on the time that you are really that being addicted into it, then it is something that gives out that urge that you will really be liking to play no matter what. Self control and discipline o which you will need.
It depends on the stage of gambling addiction and it will be individual for each player. Since gambling addiction is a medical disease that is included in the International Classification of Diseases, it is accordingly treated only with the help of medicine.
Even with medication it can't be controlled, if the person isn't ready to do it. Counselling is a major means through which people were made to self realise the mistake and then keeping themselves active on other things makes them come out of addiction.
