Sleep Thru The Night

I'm very tired yesterday night, slept from 10pm until 7am! Of cause, my girl still kacau me on and off at midnight, but I didn't wake up to on my pc and check email & etc was the most strange. My body usually will automatic set alarm to wake me up at midnight. And I usually has no problem to wake up immediately when the time is arrived. Wonder why this not working at yesterday? haha..I think I really need more rest though. :p
