I also have been told about the link between poor sleep and worse fibro symptoms. However, I have not been told about not napping. In fact, my doctors have actually told me to get sleep when and where I can. For me, sleep is a major problem - it doesn't matter whether I have napped during the day or not, so when I feel that irresistable urge to close my eyes for a few minutes, if at all possible, I do it.
