Another article from the FibroFiles folks, hoping it will help someone.
I have (thanks Amazon delivery!) a vibrating full length massage pad that I find helps enormously when I feel overwhelmed. I had thought the variable vibration was distracting my over-stimulated nerves to the point that they gave up and took some time off. I know it helps me rest and sometimes even sleep.
The pad I bought was not expensive ($60, I think) not fancy or very scientific technology. I like simple mechanical solutions to my problems. Too many possibilities or too many decisions overwhelm my foggy brain 
I find that it helps and hope that it can help someone else to experiment. My husband chuckles kindly at me, calls me his gizmo girl but always supportive and sees the benefits. RA:)
