You can never quit gambling for good once you have tasted its essence. All you can do is make short pauses but in the end you will start gambling again. This is been seen over and over again in many people cases inclusive me. When there is no hope of getting money then we come back to try luck this is bitter reality. This is one way road once in then you are on it.
Yes, we actually having fun when we are lucky enough when we are winning the game. But not all people can't stop playing after winning. Some people dont want to bet again after winning so that they will not lose of what they win, well for me that is fine, and some people are betting again after winning. It is really depend of a person of what they really want to.
