block your internet
That will help for people sometimes but not always, because see it is like you leave the college because you do not like a teacher. You have to cure the disease friend, stop using internet also means you can not earn anything then. Better block gambling sites. But that too not effective in my own experience.
Since you are the one why blocked it, you can always unblock it anytime you feel the urge to gamble again. You are just fooling yourself for doing that. The best way is to find a professional to help that can guide you to cope out of your gambling addiction.
why you don't bring someone who know how to block sites from your computer and that will make you enable to connect in any site of gambling and because is really hard to unblock them you will have no chance to return to gambling maybe if you buy a new computer :p
