It's really hard to stay away from gambling if you addict into it. Like me, i'm really hard to stay away from gambling. Even i promise to myself but still i come back into gambling. My advice is go hang out with your friend, it's works for me.
How long you've been gambling?
i have been gambling for ~3 year i find it easy to control myself, whenever there's urge to gamble i just go watch movies or play mobile games.
This means either you have never fall into the gambling river, or you are too strong and have the ability to control yourself from gambling at your wish, because I have seen too many people and its really hard to stop once entered and started playing gambling.
