How can i learn/train myslef to sleep less and not feel lethargic.?

Question

i read how 90% of people oversleep, i would like to sleep 4-5 hours a day. are there any great websites you know that can help me? does anyone here sleep less that 4 hours a day, on purpose ?

Answer 1

you shouldnt sleep that little nor should you sleep to much.  4 to 5 hours of sleep isnt enough but more than 8 to 9 is to much
