Let me tell you my schedule. I go to school from 11am to 4pm. Work from 7pm to 12pm. After work i feel fine, no problem. During the day, i struggle to wake up, difficult to pay attention during class and by 5pm i NEED to take a nap. I'm in my early 20's, 5'10 175lbs. Why do i feel like im in my 50's? Remember that feeling when you were a kid, when you would wake up and JUST GO! I want that. My tiredness is really starting to affect my school and social life. Can anyone help? All advice and comments appreciated. Thank you.
