If you said people should go on a routine checkups, in my perspective, this should basically be for people that needs it and who knows that they're gambling out of control , near addiction or gamble addicts, it isn't necessarily for someone who keeps him/her self on check while gambling.
how would you know if you need a therapy if it has not gotten to a level that it's obvious? perhaps I would say people should always check themselves naturally on how much well they have been doing before the gambling and how much they are doing after being in gambling hence always being aware of yourself is the ultimate way to cope gambling habits.
Additionally, if one notice that he or she has not being doing too well since they got into gambling what they should do is start a new habit that can overshadow the existing gambling habits, and this habits could be something that requires time and creativity that's the best way to cope habits not necessarily going on a therapy.
