though i can manage myself by sleeping 4 hours only,but i am feeling sleepy during my college hours ,,how did peole manage your sleeping pattern.......giving maximum possible time for studying

in nights we should sleep atleast 9hours and we conserdation keep on studies

Dear Koka Ram

I think that a 4 hours sleep a day is not sufficient for a normal human being, a sleep of arround 7 ot 8 hours a day is fine but as you are a student try yo make it 6 hours a day. I heard some where that a sound sleep from 12 a.m. to 5 a.m. is a must and after that take a one hour sleep after your college is over, this completes your 6 hours.
