I have spasms too! It can be so bad at times that I asked my doctor about Parkinsons. He said no to that (I can't remember if he tested me, my grandfather had it so it does make me nervous) I did take the Magnesium and it does seem to help. The spasms don't keep me up at night but they are embarrasing during the day . How do you explain a sudden twitch. It seems the more I worry about it the worse that they get so I have tried to relax about the whole thing. There are so many things that I just can't control with Fibro that it just gets overwhelming at times. I am working on destressing , I hope I'm successful.
