It's all dependent on the user but we're not on the same characteristics we can quickly get over. So there are people who will need medicine or support from family including others.
Yep, it is true. Not all people can accept their mistakes and be aware of his addictions. Some people needs advise or special approach to make them realize of their wrong habits. Advise or suggestion from their close people like family members sometimes doesn't work for severe addicts. So, they must go to special mental treatment experts/professionals.
Professionals that can give them the necessary approach on how to deal with their addiction. Because most of the time the gambler will be in denial stage and whatever his family members are advising on him will be rejected. He will be angry to everyone around him and that I think will be one of the hardest stages in addressing gambling addiction.
Anyway, on my part, I am positive that I have the control with my gambling habits. Because I only gamble from time to time and only use my extra money. So far, I haven't gambled my money for my basic necessities. And I hope to keep that way.
