After quitting gambling for a while, the brain adapts to the situation and the addiction fades. However the person needs to replace this addiction with other activities. If they start playing again, they may fall back into the same cycle, so they should never play again.
That’s the challenge on gambling abstinence. It’s very hard to resist gambling if you saw a trigger that will rekindle your gambling urges.
This is why gambler should not use their personal info such as email and mobile phone when they register to the casino to avoid opening a casino promotional mail or message that usually offer attractive bonus.
You need a total offline life if you want to get away with gambling addiction.
