How can I play world of warcraft without falling asleep?

I play world of warcraft for 24 hours a day, and after the 24th hour, I fall asleep, how can I prevent this from happening?

Answer
Dont play so much, you are going to damage your health. Without any sleep after a extended time can actually be fatal. If you want to still play a lot take breaks every few hours and nap.
