Seek the help from your family or the professional.
Addiction is not a disease...It has something to do with your brain, and you won't take medicine to cure it, only therapy and advise from a professional... An addicted gambler could still think, only that when his addiction attack, he gave in to it... It is curable and you your self could cure it...
if its something wrong with our brain then that person is need to go to therapist and needs to be ask for help so that person will not just thinking about playing gambling. i think the therapist will do it and will help that guy as gambling addiction is not like a disease and its need to reprogram our brain.
