Those who lose their self-control over themselves can no longer be normal we call them addicts. In the case of gambling, many people are seen who are addicted to gambling. They forget their family and focus only on betting. At some point, the gambler loses money and becomes even more depressed. There are some gamblers who try to gamble even if they borrow money. In short, if you are addicted, anything is possible for a gambler. From my point of view, if you cannot control yourself, then gambling is not for you. Quit gambling as soon as possible. Keep yourself busy with something else.
Only one thing will make a gambler lose control of his wager and that is if they are dealing with debt after they have used alot of money in gambling and most or the thing has gotten into them that they can't get out it anymore. It's like a jail they are trying to break out but finding it difficult to leave. An average guy with street credibility knows that you can't escape loss which is why you have to gamble with what you can afford to lose.
It's easy to quit gambling and at the same time it's not easy, if you are the type that gamble with little amount of money, it's going to be easy to exit if you cut down your greed from beginning but if you are greedy and use much, when you use a lot of money, the loss might be harder than you think from beginning. It's funny and sad that some people used money like school fees, money for business and other savings that are very important to them to gamble and that's very wrong perception of gambling.
