It seems I have 2 types of fatigue. Or maybe it is one but causes the other. I get muscle fatigue and whole body fatigue, like I just ran a marathon or I'm coming down with a terrible virus and I just want to go to bed. I also can sleep 8 to 10 hours a night and wake up feeling like I didn't sleep at all. My mind is working and alert but my body doesn't feel rested. I also get tired as in sleepy tired and have no other choice but to nap. I have to take a nap every day between 10 and noon and then an hour rest in the later part of the afternoon (around 4). Sometimes I feel rested after my nap, sometimes not.
