Op, gambling itself is addictive, if you are going into gambling you should consider many factors which are addiction and money wastage, nothing will stop a gambler if he doesn't satisfy his or her urge, a gambler will stop at nothing, do you know that you might be addicted to gambling and still think that you are normal, the problem with gambling is addiction, we know this part of gambling can not be curtailed, so which way, I have a brother who is much more addicted to gambling, I told him that I will like us to discuss about his gambling habit, we started the discussing, I was telling him the possible means to stop this addiction, he said that he will stop at nothing until he win big, that's to say that he is not considering his loss but focus on future winning, what will be the possible advise for this kind of person.
If you care about your brother, you need to open his eyes to what's going on. Most likely he is already so caught up in his dreams of big winnings that he does not control his spending on gambling. If your brother can only stop after he loses all his money, then he needs professional help immediately. If I had realized that my brother had a gambling addiction, I would have definitely helped him.
@Promocodeudo it looks like your brother is in a serious condition and needs to be treated immediately. If he continues like thats, he is worried that he will be mentally affected because your brother seems to no longer care about anyone around him and is only focus on winning big at gambling, possibly the big thing is that if he doesn't get win that, he will experience stress and maybe now your brother has spent a lot of money chasing his losses, advising people who are addicted is just a waste and I agree with what @madnessteat said to immediately Bring in a professional center that can handle this if you care about your brother.
