*I'm ruining my life with wow

Ever since i got Wow almost 2 years ago, my life has completely changed. I was often playing from 5pm to 1-2am on weekdays, just playing... it is so dam addicting. Although i still was keeping my grades up in school etc.

But not, since burning crusade has came out, im really messed up. I play to 4-5am, missing school the next day due to messed up sleep patterns. This is messing up my education and so is the fact that im playing so much at home that i dont get any homework done either.
Now im starting to notice that from looking at the screen too long my eye sight has gotten really bad :S cant see half as well as i did before TBC.

Im not sure if anyone is experiencing this addiction quite as bad, but id love to here from people who are, and mabye what theyre trying to do in dealing with it. Im about to put on parental controls to help mabye control my playtimes... not sure if thatll make it better or worse :S

cheers
