Yes, it requires openness from the gambling addict to tell his problems to the people closest to him. That way, they can work together to find a solution and get started so that the gambling addict can see that there are many things he can do besides just gambling. And when more things can be done, and he is serious about doing them, he can solve the problem well.
That open communication can speed up the process, even how tough it is but if both sides are willing to work hand in hand that addiction can be eliminated in a much quicker time frame, I see that there are addicted gamblers who are always denying that problem making it hard for someone to give the help that they needed.
If they can just let it go and try to do other things that may divert their attentions, other activities can lead them away from any gambling related practices.
