reading pleasure and nightmare

this week is my reading week. i've gone crazy for books. been reading nonstop everyday for the past 5 days.... i reckon i've read over 30 hours. finished the phillip pullmans' trilogy. Northern lights, subtle knife and the amber spyglass. and half of jeffrey archer's 'to cut a long story short'. oh my gosh? i feel my eyes breaking up. everythings so blurry now. it must be the 9 hrs non stop reading...
