Of course in any case such as in gambling you can get out of addiction if you can agree with yourself not to do it anymore, and this mindset will be able to come out when you really realize that what you are doing is something wrong that most other people avoid and that means any addiction can be overcome if you basically realize that what you are doing is wrong or that means that recovery must always start with awareness and desire from yourself.
If you still have that control over your emotion then it's aggreable that you can still quit your way, though there are different levels of addiction and those who already suffer from deep addiction needs help from the professional, as even how hard they will going to try the dominance of gambling already pollute their minds.
People who find it difficult to get out of addiction is because they have to fight against the expectations that they put on their gambling activities, or what I mean is that it will be very difficult for you to get out of addiction if basically your goal is to come to gambling is to earn,
Becuase that's also the outcome of being greed, thinking that money can be earn easily and quickly, you attached yourself and your engagement is no longer controllable.
And on the other hand I think most of those who are already addicted do not realize that they have entered the addiction phase so they think what they are doing is normal and does not matter when in fact the wrong approach they are doing is causing a lot of problems in their lives, especially in terms of finances, so all of that will be overcome if you really realize that what you are doing is something wrong.
Still in denial stage, most of those addicted gamblers are in that phase and not willing to be corrected, they keep trying and the outcome still unfavorable to them.
