Sleep, as always but it's my fault for not getting enough of it.
"Kick the sandman in his sack. Stay up late, insomniac!"
Seriously it's rare for me to sleep more than 5 or 6 hours. My body has been conditioned to wake up after 5 hours of sleep, so even on weekends I wake up after that amount of time and I have to force myself to sleep. Total nightowl right here...
Toughchick401: hope you are able to get some sleep soon!
