Not easy but not impossible. As long as you have a strong intention to stop gambling and strong and unyielding efforts, you can definitely stop gambling. But stop gambling will not be done in a short time. And most people who fail in their attempt to stop gambling is because they stop trying half way. In other words, they have not failed, just stop fighting.
At a point we get busted than it could be a turning point of our life to realize that what we are doing with our hard earned money and this is not the way to earn for our expanses. I also changed my mind about gambling after had a very experience and now I also not active on gambling like before but doing it on the point of fun.
