Control your thoughts and feelings and don't allow your thoughts and feelings to control you (actions and behavior).
Achieve control by focusing your attention for 1-2 minutes on thoughts and feelings to bring them into your conscious awareness.
Negative thoughts and feelings will dissipate, while positive thoughts and feelings will be amplified.
If at first you have minimal results, do it again. Practice. Similar to paradoxical intention used by Viktor Frankl, Austrian doctor.

I am always irked by our society's readiness to classify behavioral patterns as "mental disorders."

Although they call it an addiction, other studies say there are also some benefits that come from gaming

The strange thing about that is I was addicted to pinball in my twenties. I managed to break out of it but it was debilitating. Why now I ask? I am sure there were others like me at that time but we weren't gambling so I am guessing the addiction went under the wire. The symptoms were identical to those cited above.

Gambling has always been an addiction for some. English aristocracy have throughout history redistributed their wealth by gambling away their entire fortune....and less wealthy gamblers have always been as badly affected. In the end it is a freedom of choice decidsion .. what can you do to prevent people self harming?

I admit it : I was addicted to "GAME of THRONES"

No different than alcoholism

Treatment is difficult because they often return to a circle of fellow addicts and get right back into it...it is not as easy as turning off the device...

Any behavior that activated the brain’s reward center can be as addictive as drugs
