What a bad routine in sleeping...

I can't deny I'm too good in this... on-off sleeping.
Yesterday itself i slept for more than 12 hours on on-off basis, it had been a long time that i never on-off sleep for so long with all the busy schedule on going ...
Friday evening where I just reached Johor Bahru from Singapore to sign my new offer, I slept about 5 hours until my house-mate woke me up and asked me to go for a drink as a celebration for my new career appointment.
From that moment we party all the way until morning about 7am and straight head for a breakfast. After that what else, I slept until 330pm, and not to be confused, it's Saturday already. I managed to stay awake up to 930pm, and finally I can't take it anymore, lying down on my bed and SLEPT!! I woke up just now morning 7am and now I don't feel zzz, but later I'm going to work on night shift, hope that I manage to stay awake later until tomorrow morning 9am... Is going to be tough I think since I had left work for more than 1 week...
Anyway, I had tender my resignation, so it won't be too hard for a resigner to find excuse to work out of focus...keke... Is kind of irresponsible though, but what can I do, human behavior...
Kay, I need to do something else now, see ya...
