Not even once

There are plenty of options to prevent you from experiencing those losses and those feelings. First one is not to have life-changing funds on any casino, then to avoid games that would eat away your balance in minutes. It's easy to fall in such a trap with slots or dice, far harder when you're only betting on sports. You might feel the urge to gamble because you have lost a game, but you might be in luck and no game would be up for playing. For example, I bet on horses,  by the time I would experience a row of losses, most of the races would already be over, so I would need to wait for the next day. Enough time to cool my head and keep my actions in check.
