So my question, are you willing to go to this length for self inclusion because you are afraid that you will want to comeback to a casino and have the feeling of winning the jackpot and then become what others experiencing beginners luck and become addicted in the end?
Yes of course, I would do everything within my powers to get myself safe from becoming an addict which self exclusion is one of the things would do as long as it works for me not to get addicted to any kind of gambling habits because once you get addicted it becomes very hard to leave such habits.
OP what the person in the story did is the best thing anyone can do to help themselves especially when you know that people around you already got involved in what you are preventing yourself from becoming so you must do all that it takes even it takes you to get banned from all casino so you don't go there anymore it's still a good idea.
