create something new in your life. you will never stop thinking about gambling until you find something that can become more interesting in your life. in my opinion, an even better solution would be to join a group around your new hobby.
I think once the person becomes addict to gambling, there is nothing left for him in this world which is more interesting to him than gambling because he is earning money from gambling and there is no such other activity as much easy as gambling is and from where the gambler can easily earn money with putting much efforts, so he decides to go for gambling and to end up like this.
