Hallo,
wolltet (bzw. müsst) ihr früh aufstehen und klebt um 03:00 noch am Bildschirm?
Dann schaut euch mal das kostenlose Programm an, welches den blau/rotanteil des Datensichtgeräts (EDIT: Monitors) der Tageszeit /des Sonnenstandes nach anpasst:
f.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.
It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.
peace
