I just had cfs sudden onset on thursday and since then I could not sleep at all! I'm just not feeling tired, but my head does not allow me to get only a little bit of sleep. It's that every time I fall asleep I get some kind of shock in this moment and am wide awake again. Do you know what I could try? Is this ever going to change to some version where I might get at least some hours of sleep now and then? Thanks!
