You never stop,you play while you have money it is addictive as a drug when you have you use,when not you try to find her,in gambling when you lose money you find way to find money when you lose everything you will stop.
It doesn't occur to a lot of people when to stop actually and so they go all out until they are nose deep into it and their pockets are drained and when nemesis finally start catching up with them they quit because they have nothing left to offer. That's a terrible lifestyle.
It's hard if you have that kind of negative attitude, you are not planning well prior to gambling and you might lose everything you have because you love to risk with a careful planning. Money is important and in fact it's the main reason why we are gambling but not knowing when to stop is very irresponsible which would only make you expose with some bigger risk.
