For example, i don't play a lot or for long time (i play games spot during my free time), so i have no idea about, but i trade forex all day and when i had a significant loss i usually turn off my Pc and i go out for a drink , just for not run behind loss.
For me,it is easy to spot a gambler addicted because im also a gamber but controllable,you can easily find those person if his an addict in gambling if he should not take a bath when he played game's and so many beliefs in his own self,of not wearing unlucky shirt,or other kind jewelries so that the goodluck will not fly away,and most worst scenario is by bet all his asset including all his properties to sustain his vices.
