I usually play WoW 5 or 6 hours a night and most of the weekend, but that's more because I have little else to do at the moment due to it being summer. I will still go out with friends when the opportunity arises and my job has been unaffected as I still get 6-7 hours of sleep a night minimum which I find is plenty. I still go waterpolo training every Thursday and do press-ups/sit-ups each evening so I stay in shape too.

I wouldn't want to quit playing WoW though as I do enjoy it and there is a real friendship in my guild (we have an age limit of 18 to make sure we are all mature people and we can weed out all the "leet kiddies" pretty fast and we have a good mixture of men and women).
