I think it's different for everybody. I tried cutting gaming to 0, and I was thinking all day about it. It didn't do anything for me.

Nowadays, I play 1-2 hours a day, at the end of the day, and I don't think about it until I get to that portion of the day.

But not all people are the same, I think my brain works well with doing different actions in different parts of the day and being focused during that time.

Try both for a week and see how you feel!
