When I was doing heavily gambling I was in similar situation whether I was stopping at some profit or at loss but was coming back after a while. This is gambling which doesn't let you stay calm in either case you will try to recover or make more profit. In my opinion large number of players go through similar situation like me.
If you will win you will try to win more and if you loose then you will again gamble to recover your loss and that is a human nature and that makes him to go for gambling again and again as most of the gamblers lack self control which is very important in gambling.
and as long as we can not realize and see the truth that playing gambling in every time can make us getting loss more big, then we can not control our self from gambling. for people that can stop their habit in gambling, they should continue to stop it and don't think to playing gambling again because if they are trying to playing again then its difficult for them to stop and they only want to playing gambling.
I don' think we will have to stop when we have no problem in gambling, it's given already that we lose but the entertainment we get is something we can value of. I temporarily stop gambling before due to bad experience which I lose more money than I can afford to lose but I'm back now with confidence, it takes a hard fall before I realize that I'm not doing what should be done to stay safe in gambling.
