I had 3 months (the longest time ever for me) without gaming, but this was a few weeks ago. I relapsed when, I reckoned, I couldn't see any noticable improvement in my life or relationships.
The loneliness was unbearable. I'm not gonna lie, I spent most of my recovery time sleeping, watching movies and reading books, oh and listening to music.
My goals are to WRITE, FINISH COLLEGE, and BECOME A BETTER MUSICIAN, but during those 3 months it just looks like I did things to ease my pain. Movies are a great way to escape (maybe not as good as V-games but still...), sleep is great for escape (but at least okay in healthy amounts).
So in another words, I just wasted my time in other ways during those 3 months, with a admittably significant improvement in the quantity and quality of sleep I was getting (who stays up till 7am to read a book, seriously? lol).
I quit again for a week or so, gave away my computer for a while, and started contemplating how to sell all of my old V-games on Ebay. I helped my parents set parental controls on our family's router, so that it would kick me off the internet at 10pm, 11pm on weekends. However, my Addict Brain succeeded in reacquiring my laptop to play videogames, which doesn't require the internet for me to play games.
Anyway, I was wondering how long it should take to go from "clean" to "healthy" and "productive". Not gaming is a sort of success, but maybe I'm too impatient and want to see my life change instantly.
