is it coffee-effect??

*sigh*
Find myself can't sleep again tonite... it's 4am... and guess what?! i havent even touched my bed yet... i dunno why, i keep telling myself not to sleep... and so here i am... with eyes wide awake, tired body and mind.... but cant sleep.... i really should hold on to my words that i wouldnt drink anymore coffee except during the critical moment...
I think, i'd better study now.... and hopefully i'll be able to sleep soon, coz i'll be having a class tmrw... and i find that keep awake for too long is not good for my mind, since i started to think about unimportant things...

nitez everyone....
