I did my gaming days and I regret it now. I should have spent more time doing things that didn't require staying inside the house all day long, things like sports, enjoying the nature, going out with friends, playing and instrument like piano, anything is better than staying inside and playing games.
The way I got rid of this nasty habit is by selling all the video games and console and going out a lot. You need to say stop and keep it that way. Find a sport you like, try to play a musical instrument, you can even try fishing or photography.
There are so many things to do outside that is mind boggling. For example my newest hobby is flying drones in the field. This is so great and help me de-stress.
Take care!
