The will to quit gambling is always being beaten by addiction. No matter how you wanted to quit in gambling, if you really get addicted, you will return even if you have stopped for how many days, weeks, months, years. There is a time that you will go back to your habit.
Of course when gambling was once part of our lives, the desire to do it again, even if we have stopped for a relatively long period of time, will reappear. But, with my personal experience, the memory of a past defeat that is so bitter can be a controller when the desire to gamble over limit begins to arise in the present days. I can't quit 100% but I am able to control my gambling habit.
There are a lot of reasons for that, it is in fact depending on your environment, your nature and company, i think that if you belong to such compalny where most of the people are gambler, then it is really too much difficult to quit gambling so easily they will compel you to play gambling again and again which will become your addiction and which will then become too much difficult to quit playing gambling forever.
