If I..
Sleep late -> Waking up early -> On Time for tram

If I..
Sleep early ->Wake up late -> Miss tram >.<

HOW CAN THAT BE???
=.=

Let's also look into my energy levels...

Fewer hours of sleep : Alertness level is higher in the morning -> drops after lunch (zombie-nized) -> rises at about 3.30pm -> quickly drops after 5.30pm.

More hours of sleep: Alertness level is lower in the morning (extra blur) -> gradually rises throughout the day -> drops in the evening (still experimenting)

sigh...
So is sleeping earlier + more hours really beneficial?

My bioclock is obviously chaotic.
