I'm not sure that quitting gambling is the best way.
We will not talk about that particular case when a person came to gambling and immediately won a lot of money. After which he left gambling forever, because such lucky people are literally 1 in 1,000.
I am sure that if someone has strong self-control, then he can periodically gamble for small amounts and thus relieve stress and lift his spirits. It is still better than alcohol, and there is a chance to win even more money.
Or maybe 1 in 10000. It's difficult to quit after winning a big multiplier. Once you taste that sweet victory, you will be drooling for more. I experienced it many times, and I still play slots because I want to achieve it one more time. But I think it will be my last time if ever I get it again. The stress given by a losing streak is not easy to handle. There will be a point when one should just walk away from playing slots because it's not entertaining anymore, but more like a stressful type of game.
