Please note that the patient will resist to the last. He will give counterarguments. For example, that he will get rich in the future, he’s just not lucky yet.
What other arguments do you think the patient will give? How do you respond to these arguments of his?
They are professional enough to handle this kind of situation and of course there will be a resistance, and it's not an overnight rehabilitation.
This will take months or even years before that clinic successfully change the addicted persons, as long as they hire professionals and they maintain the quality of their clinic, I'm pretty sure they will succeed on this. It's hard to say the argument for this one because we are not professionals and doctors to handle addicted gambler, we can only tell general advises but with a good approach, i think only professionals can do this.
