Perhaps, we need to stop for a while, and as you said, it's better to go home and take a rest and don't forget to eat something. We can come back to the other day, and we don't have to push ourselves to keep playing while we don't know where is the luck. Accepting your lose in that day, don't regret the loss, take a deep breath and then walk away from the place is the best thing you can do.
There is always tomorrow. Don't die gambling and no stopping, that is over addiction. you can call it a day when you lost several sessions and just play the next day. The reason is that you just too exposed and emotionally drain that you will have a greater tendency of rage betting.
Yes, that is for the gambler who can realize that he doesn't have to use a full day for playing gambling. Besides that, he never plays with too much money because of chasing the win money. That is an example of a good gambler who could become still aware of himself. We should keep trying to be that person, so we don't have to lose much money in a gambling game, and we could also save that money for the next day.
