With a strong will, feeling wanting to gamble can certainly be reduced that we can finally stop completely from gambling. At first it be difficult, but if you are used to it there is no taste anymore feel to gamble. Well, dealing with people around can help us in early stages, or maybe a vacation with people we care about will help us forget a gambling.
This should what a gambler have first, he should need to have that will to quit. Because even if he wants to quit but he doesn't have the will to do so or he is not doing anything to quit, he will not be able to quit. But if he is willing and he really pushing himself to quit by doing something to exchange with his gambling activity, he can quit a little bit.
