Do you know  that there are problem gamblers who would follow this your rules and still not be able to quit their gambling addiction? Those are gamblers who are yet to make up their minds and stay committed just like you. I don't think your rules were the one doing the magic for you, but your decision and commitment to see it work is what has helped you so far and I absolutely love it. Do what works for you mate, I am usually happy when people make efforts to be a better version of themselves.
