Stay awake

Ah!! I cant sleep after come back here.. My room's spoiled air conditioner cause me keep awakening and i get jet lag! omg, i dun like this feeling although it's first time for me. I was slept early in the morning yesterday and woke up around 2.30pm without realize that it was already 2 something on the clock.. i was awaken by my mum's shouting. Worst of the all, my body clock thought it was only 8am in the morning, why wake me up so early??!!
