You don't need to quit yourself. Maybe you are playing just for fun but still addicted to it?
That you just change with a small "change".
With just for fun you can stop when you want to stop to gamble, but if you have a target in the gamble you will not be easy to stop someone's addiction to gambling.
Fighting our own mind will be necessary to combat addiction and no exception to gambling addiction. Sometimes we can do it by our own effort but at the other time, it takes the help of others so that we can get out of bad habits that have already attached to us.
