Addicted to World of Warcraft, longing to go back?

Go back if you can find a way to moderate your time. Set aside maybe 2-3 hours on weekends and don't play anymore than your set aside time. During the week don't spend more than 1:30 hours. My friend was an addict so I told him to do this. He built his weekend time down from 3 hours to 2 hours. During the Week he plays 1 hour. He leveled up to the highest level(I don't play) in 2 weeks.
