I notice distinctly apparent changes in myself under sleep deprivation: cognitive skills increased, mood increased, focus is typically good and distraction is no longer a powerful nemesis. My first experiments involved a period of no sleep for approximately 5 days during which i took some interestingly creative yet mostly incohesive notes. At current i am a college student and i have time spread throughout the day to do as i please. I wish that i could never sleep but i am a realist. Ive learned that a typical circaidan rythm, ie when people will most likely be tired, is from 2-6 am and pm. Whilst not sleeping at all, i have noticed a severe onrush of fatigure around 6pm and also one around 9-11 am. What i am looking for is the optimal schedule which would yield the least amount of sleep possible to still be fully functional. I recall Einstein took naps frequently but did not sleep through the night? some input would be appreciated.
