That's the key problem there. The only reason they get addicted is because they don't want to change. Those who truly wanted to change was able to overcome their addictions. Others are just a lost cause. You need strong will and a reason (such as having a better future) to get out of addictions. There are people that can never overcome addiction because they no longer have anything else to lose in life.
It seems to me that you need to find something else and you will not even have time for gambling. For example, I did not think about getting rid of gambling forever, but sometimes I do not have much free time that I could choose a bet.
The whole week was busy with business, and I completely devoted the weekend to my family, in this case I do not even have to think about the negative effects of gambling, on the contrary, I already miss it and want to find time to play a little, so if this is all in balance, then you will treat it accordingly.
