Hello So I just wanted to check-in and talk about my fatigue and to see whether it chimes with others out there. In general, my fatigue has slowly got worse as the months have ticked by. Where as a 30 min jog was once comfortable, now a brisk walk seems more palatable. (I appreciate that for many even a short walk seems insurmountable). However, it is work rather than exercise that really seems to make me fatigued. Doing what I would describe as 'higher order mental tasks' really has a profound effect on my nervous system. Sitting in front of my computer all day, thinking a lot, contributing at meetings, teleconferences, presentations.......they just drain my batteries to the point that if feels like every nerve fibre is trembling in my body, so that it hurts to think, and my brain just goes slow. I've had to stop playing my much loved sport, stop jogging, and now take walks as my exercise. But even walking for relatively long distances doesn't effect me like my work does. So in summary I seem to have good energy still for physical tasks that I can do automatically, but mental / thinking / cerebral tasks drain me flat. And I would add that it is not a "nice" fatigue feeling, full of yawning, arm stretching and drooping eye-lids, where I could just go to sleep. It is a "nervous" fatigue feeling, where I feel wired, agitated, like my nervous-system is on melt down. Not nice at all. Does anybody else feel they have reasonable physical energy but very poor mental energy? Is this common?
