Why do i always feel so sleepy?

Also diet will change things a lot, and exercise. If those are all fine, I'd try figuring out how your sleep quality is - maybe its time for a new bed/pillows etc

You are probably hitting a time in your life of fatigue, either you work to much, or your really stress out of something now or back then, go visit your physician and find out.

i guess it's not just about how many hours u'r sleeping but it's also about what time is ur sleeping time...if u are sleeping late at night lets say 2 am or 3...even u sleep 6-8 hours u can experience sleepy hours during the day.try to sleep early thats my suggestion and compare the difference...and aside from that u need to do something that will make u busy not just to watch tv,if u r lying in the bed of course u gonna be sleepy...and avoid to much food that absolutely gonna make u too sleepy...i hope this would work...good luck!

You are either having a chronic fatigue syndrome or you are just lazy.

Most people need 8 hours of sleep. You are probably not getting enough. Also, if you are not getting enough nutrients and are not eating healthy, balanced meals, you will have less energy (because you don't have enough of the right food in you to sustain you)

Is it too hot in Nigeria ? Go to bed at sunset and wake up at sunrise. You will not be sleepy the next day.

You're either depressed, just under stress (practically the same thing), not getting enough sleep (maybe six hours isn't enough), or you have some weird disease that I strangely cannot name. Hope you get better, anyway.
