That's why everyone will say don't addict to gambling, once you addict to it there won't be any limits for losing. You need to control yourself while gambling otherwise you will end up with no money. Then it is time to give up gambling.
Some people can never beat the gambling addiction because they have strong genetics to prone to end up as heavy addicts with absolute no self control at all. Those people need to be put into professional help and possibly use medication.
Once the medication makes effect, you can start removing it slowly. But real addicts can never ever gamble again, they aren't capable of gambling for fun sporadically.
Yeah, it definitely seems that gambling addiction or addictions in general can be genetic. I wonder how much of the addictions are genetic versus acquired through circumstances or setting that we put ourselves in though. It definitely is a lot easier for someone with an addictive personality to get tripped up on gambling though.
