Not being able to sleep....in office

Today...or should I say, tonight is my turn to work nights in my office. All my other colleagues have gone home, and I'm the only one staying over now. Usually, I don't really mind working overnight, cos firstly, there's not much to do during the night anyway, and secondly, I end up watching TV and surfing the net most of the time. The best part is...I'm doing all the above in the open...there's no need to tou tou mo mo at all....and even better, there's also usually some time for me to doze off for a while. But strangely, tonight seems to be quite different....its already 0430 am, but I just can't get to sleep at all!! Its like whenever my mind enters the 'blackout' zone, my heart just suddenly beat rather fast, and the feeling is not unlike that of me getting a sudden fright/scare. Its totally weird...cos I'm alone in my office....and I usually dun get this feeling! But perhaps its has something to do with me not getting used to working nights alone...i usually do it at least with another colleague. Hmmm...I'm not too sure if I should be scared or not....fortunately, I'm still pretty calm though...which isn't often the case. Usually, if I were to encounter this, think I would have completely freaked out by now. I know! It must be the heavy supper which I ate earlier during the night.....yeah yeah...blame it on my nice colleague.......

Anyway, three more hours, and I'm off home for a truly comfortable and good sleep in my bed...can't wait boy! Will continue to surf the net till then....maybe I should look for more 'Friends' personality quizzes while I'm at it.....
