My first thought it anemia..

Are you getting enough protein in your diet?

Could you be a "growing boy"? My sons always slept when a growth spurt was happening....men grow for a long time (and I am not talking emotionally

Do you have any other symptoms...sore throat, swollen glands, slight fever? Could be mono...

Depression...boredom....just plain doing to much fatique time to catch up rest?
