Kinda relate on this, almost 1 year being addicted in an online video game. Can't almost eat, sleep even my personal hygiene I almost neglected that. I realized that is causing a big problem and I don't have even savings at that time because I spend it all my money in a video game and wasting time as well. When I got marriage I feel regret that even small savings I don't have. I never realized that before because all I wanted is always having fun.
I used to play MMORPG and there were many people like that in my clan and some of my opponents. It's easy to spot them in game because when you logged in they were always there. I talked to some of them and one guy used to always take holiday jobs abroad which made him earn 2x the money he would in a normal job, then in Autumn he would come back home to live with his parents and tried to make the money last till Summer. The rest of the year was MMO even 20 hours a day with only 4 hours of sleep.
