@Mij, that's what we are discussing here actually - resting def makes me worse, if it's more than half day (after active few days). I tried to rest preventively, it makes me worse Sux. it will turn out GET is best option for me (you did not hear me say this ) @JaimeS, I am 31 and have ME/CFS since about 12 or even before, I remember this pattern from very early, even when it was extremely mild before my 20ies. It's simply like choosing between 2 evils. sometimes I enjoy activities once I warm up, but starting them is torture. staying in bed even worse.
