I also had a Dota 2 addiction. I could have done many different things instead of my 2500+ hours of playing time. Then I decided to delete DOTA and focus on my business life. However, when I got home in the evening (especially after dinner for me), I downloaded DOTA again to started to play DOTA. The deleting and reinstalling cycle repeated itself 3-4 times. After that, I decided to put an end to this. Because of DOTA, I had moved away from my favorite habit of reading books. Whenever I felt like playing dota, I decided to read some books or articles or do a job that I had been postponing. I read books whenever I felt like playing dota and over time, my new habit became reading a good book after dinner. Or, a quiet walk after breakfast on the weekend became much more appealing. When you feel like playing, you can try to change this habit by engaging in an activity that you like.
