Answer by  Travis404607 (3916)

Fatigue and headaches are usually caused by environmental stimuli and nutrition. Make sure you are drinking enough water. Also, make sure you do not have any carbon monoxide exposure, as these are classic symptoms of carbon monoxide poisoning. Have your furnace checked if you suspect this might be the cause.
