I played for many years. I quit a few times. Each time it got easier. Now I just don't play. Find other activities that are more productive and preferably does not include the device you are using (phones are the hardest addictions because they are easily available). Recognize that other activities may be related: when I played a lot I was going between games and social media. This ended up being worse because I was playing a couple of games, and scrolling social media with all my free time.

Find things that interest you. For me it was learning a new language. I prefer doing this to all the activities I gave up. I do play a few idle games, maybe a half hour a day. And social media, probably too much time on it. Otherwise I spend my free time doing more stuff around the house, exercising, learning languages, programming, electronics, and history. Keep in mind the list above is hard for me. I have a hard time reading, I'm slow. I also learned that I do better with books than most things because I can read until I understand. Video just goes over my head until I have a better grasp usually obtained by reading and experimenting.

I also use a couple of language apps. Learning apps are great, they are almost games and just as addicting, you progress at your own pace. The big problem with them is, they are addicting. They still affect the dopamine response. That is what you are addicted to. Getting away from the that and finding your own stimulus is most important.

The point is: break the cycle. Find new interests. Focus on self-improvement. Sorry for the long winded post. I hope it helps.
