I have fibro too and when i have those times I can hardly move my DH just grabs his raincoat. he says i am more reliable than the weatherman. after reading this post I am wondering how to tell if the fibro fog is because of that or my stoke? there are days I just want to be quiet and not even try and speak or answer questions from anyone.the right words just don't come out. never thought about what you all call the fibro fog related to that. just thought I was losing it. thanks for the question and the informative answers.
