hang over?

yesterday after my morning shift, i was so tired that i felt asleep straight after dinner! this is the 2nd time i fell aslept while watching TV series! gosh!! i think i am losing stream in my "love"! OMG!!

if that is not bad enough... i woke up at 0045hr and was unable to get back to sleep anymore! that explain why i am blogging at the wee hours of the day!

could this be a sort of hang over (from stress)?
