Sleepless in Pasir Ris

Here i am in the staff room at 0800hrs waiting for the marking of SA1 compo papers to begin. Believe it or not, i haven't slept in more than 24 hrs. Not that i was up doing something but the mind was working overnight over random thoughts which was totally irrelevant. Eyes were shut but the mind refused to switch off. I am frustrated coz lack of sleep will result in a bout of migraine. I realised that a cup of teh tarik always causes me to lose sleep. Initially i didn't wanna have a firm conviction that a harmless cup of teh tarik can cause sleeplessness but after a similar pattern each time i down one, i am quite sure that is the main culprit. Therefore, i need to refrain from drinking one during weekdays. As of this moment, i feel a heavy 10kg weight pulling down my eyelids. I hope my body and mind won't fail me while i try to be alert whilst marking those papers.
