i used to have this problem, no matter how long i sleep i still
feel tired and i dont know why. 6 hours, 8 hours, 10 hours seems
the same.
and it's pretty irritating because when you've to do sth impt the
next day, the night before you sleep early and you have 10 hours of
sleep but then the next day still feel sleepy and cant do things
well.
so drinkin water helps huh ? i know i drink very little water a
day.
and another thing is people say theres a time when it's the best
time to sleep, after you pass that hour, no matter how long you
sleep it's useless & you'll feel tired ? sth like that, im
wonderin is it true & whats that time
