Yes me too,
I also thought,like Linda,of the EMFs something like this could also be effecting you.
It's so unpredictable it makes planning anything very difficults,even if you wake up feeling fairly ok,or even good or great,in an hours time you could be fit for going back to bed.
I find the unpredictable nature of the fatigue one of the most frustrating symptoms !
sometimes for me it means having a sleep or at least lying down for a while,but sometimes the fatigue lifts just as suddenly as it appeared.
