Stayed up late and haven't sleep till late night...

Here I am..... Stayed up late and haven't sleep yet...although that I have always tell myself to sleep earlier, ended up always sleep later than expected(for e.g 2am/3 plus am). Sometime can't seems to fall asleep..
And ended up sleep till afternoon(1 or 2pm) than naturally wake up, which is NOT GOOD AT ALL, I can eyebags formed, and nevertheless, dark circles too...

Argh don't want to be like that ehhhh........I MUST FALL ASLEEP!
