Why Am I So Tired?

A four day holiday with an extra long weekend. One would've thought this was a great chance to get a good rest and holiday over the festive period.

Alas it's not to be. 

Dunno why. Maybe visiting everyday has something to do with it? Maybe hosting gatherings at home has something to do with it? Maybe sleeping late nights and waking early has something to do with it? Maybe eatin too much CNY goodies has something to do with it?

Wonder why?
