Yah. I always thought that "fatigue" is the wrong word for how we feel. Because fatigue is used to describe a healthy person's sensation of tiredness, it is misleading.

I'd like a new word. Personally, I loved the metaphor on BT about 5 years ago, that "I am superman but there is kryptonite in the room" to describe MS fatigue.

I hereby announce that the new word for MS fatigue is "Kryptonitis"
