Haha, I love how everyone speaks about WoW as if he is asking whether he should start smoking (granted there are similarities). I reckon if you can get a group of friends and all get into WoW together you will have a great time. I fondly recall my memories of playing WoW into the early hours of the morning with my a couple of my friends at their place. We don't play anymore so I don't know how hard it would be to catch up with everyone, but I hear it's pretty easy nowadays, if you're after an mmo, you can't really go wrong with WoW.
But as other people have said if you're easily addicted to things you should probably be careful, it could easily turn into something similar to a crack addiction.
