Can I hv extra hours before going to sleep?

Now, it is 2343 05s according to my handphone@my watch since I lost my NEXT-UK mali watch. I feel so sleepy. Though I already slept for one hour in the afternoon, my eyes' rod cells just can operate anymore. Huhu. Yet, two more lecture notes and one tutorial waiting for me to be completed. Hope I can wake up early tomorrow and finished them before time and to make it worse, my first class starts at 830a.m. Can't wait for Friday to come.
