Budget: set it BEFORE you start gambling and stick to it.
Also that the budget on gambling weekly should not be higher than 2 to 5% of the gambler weekly income.
Have a break from time to time, it is important to let your brain stop and consider.
Gambling should be for fun. It should not be what someone should consider to give a break for, but to be done at a very short period of time weekly.
Gamblers should not chase losses too
in my experience, if you are on the losing side while you are playing the game. take a pause, assess the situation and check where you are at your set budget. sometimes gamblers are getting lost once they are suffering losses after losses.
