Today after coming back from lab, i also dunno y i can fall alseep for moe than 2 hrs, making me feel quite headache after waking up from my nap. Maybe i dont hv enough sleep everyday, making my body wanna to compensate it n then sleep for so long then? Dunno, no idea. But, in the night, i still feel quite tired while i was busying with my work there. Haiz. Wat happened to me oh? hmmm, seem like i need to rest for a while alrdy.
