That is very true. Even though we have strict financial control, for me there are still emotional moments due to losing and when conditions like that happen we usually spend more money than usual to gamble. I often lose control when I get a big win the previous day and the next day I usually budget more money for gambling, and as usual when I get a big win then the next day will be a nightmare, and I spend some of yesterday's winnings.
Keeping your emotions in a stable state might be difficult, especially in times of the same situation as you. Recently winning with a huge amount gives confidence to each gambler and makes them think of the possibility of winning more. However, once what you thinking does not happen, it causes the loss of control of your emotions and will lead to chasing your losses.
This commonly happens in every gambler. Even for some who consider gambling as a stress reliever or doing it mainly to have fun, a lot of them end up emotionally invested in the game. Making it hard to control the emotion and forget how to control it.
