Sudoku...Argh...

Ok, so I tried to answer a set of sudoku. I finished it and when I tried to answer another, I lost my patience. I thought that I can answer it but then again the impatience within me arouse. Why am I still awake? Its because I'm setting my body clock to be awake from 9pm to 6am because I'm a night shifter at IBM...Talk about stress. Whatever. For the love of a job(huh?). I really pray that I could make this until the end of my contract.*sigh*
