i'm not ready to auto-in yet

Oh Jesus Christ, I'm so sleepy!! I have not taken any calls yet, and my eyes are really gonna shut, I can't concentrate, I can't even stare at an object...god, I'm very very sleepy.....I don't know how long will I be in agony with this 4am sked, for some it's good but for me it's not. I'm such a nocturnal person, I'm weak during the day, I can't function well. Daytime is my nighttime. Oh please help me, coffee can't take this sleepiness away from me, what shall I do? I have to stay here until 1pm, goodness that's 9 hours! I don't know how am I gonna survive.
