I doubt that you can stop gambling when you are addicted since it’s very hard to notice the symptoms due to the addictive nature of gambling. The only way for a compulsive gambler to stop is if someone help him to change or he doesn’t have any money to gamble.
I believe the gambler is not on completely addicted state if he can still evaluate what’s going on and evaluate what he needs to do.
It's very hard to stop the gambling from my experience after you become a gambler,we can reduce the number of games and betting amount.
