Exactly! Rehabilitation camps and doctors are just there to help and guide you to overcome your addiction to gambling because the final decision is on yourself and you will serve as the test if you can really overcome that challenge. As far as I know, only people who are really serious about changing their lives are the ones who overcome their addiction but if they are not serious.
Addiction or excess of anything is bad. First thing is, we must try our best not to get addicted to gambling or anyother such thing. But if you are addicted to anything like that then one must consult his family or talk to doctor. But yes that's only possible if someone consider it a problem and wanna get addicted to it.
Most of the time, these bettors didn't even know that they are also an addict to gambling. For them it is just a regular day of betting but little did they know, they are already in the deep waters. The first ones to know or notice that they are addicted are their friends or family, they should know what to do and tell their loved ones that they should put on hold on their gambling activities and consult a doctor to get help.
