Tired and Cold

For the past three days I have been two things:

• Tired
  

&

• Cold

At first I thought the tiredness was due to Superbowl Sunday and then a 3am drive back to Eagle on Monday morning... but after two GOOD nights of sleep, I am still EXHAUSTED! My mom said she was cold and exhausted for the first part of this week too. Does anyone know of a random bug going around?

No fever, no nausea, no stuffy nose or cough -- just INSANE tiredness and being cold. Not even chills that accompany a fever, just to-the-bone cold.

Any diagnoses out there?

I'm going to bed...
