Need more sleep

My plan to sleep more has failed. Maybe if I stop doing paperwork in the middle of the night and do them in the morning would allow me to get more of the natural recharge.

Time needed to recharge: 7 to 14 hours.

Heh. I still cannot believe I could sleep for 14 hours straight and still feel well when I wake up from the long sleep. I usually get headaches and cannot move my limbs properly when I sleep for more than 15 hours.
