Find something else that is fun and won't cost you a fortune. I myself stopped gambling some time ago and how I did it was by finding something else to do more productive.
Its better if you can divert yourself into other options of bitcoin like trading sites to stay away from gambling and think of profitable source which can earn additional btc. Aside from gambling you can even enjoy yourself some having fun like playing music instruments as part of other extra curricular activities that can be your hobby.
Once upon a time I am also addicted gambler, but after some incidents, i try to control my gambling. Now I am ok I have control on my play. The bitcoin forum helped me to come out from my addiction. I joined the signature campaign and started to earn money. So slowly I concentrated on campaign and I got control on my play.
Thats good. Focusing on other things will help you stay away from gambling slowly. That way you can divert your attention and wont think about gambling for sometime or maybe most of the time.
