And what do you think, does refusal to play (deprivation) contribute to recovery from addiction or is it useless?
If a gambling addict manages to refuse to play, it can certainly be utilized for the recovery process from addiction. However, the process for the gambler to refuse to play is not easy. It requires full awareness from the gambler, while in the case of gambling addicts, controlling oneself certainly requires assistance from others.
I usually am willing to abstain from gambling for a while to stabilize my thoughts and emotions. I have been addicted to gambling before, and I decided not to quit gambling but to limit my gambling. The process is indeed difficult, but once I get used to it, gambling activities can be more controlled.
