Try putting (bathing) soap bars under the sheets. Several. Unwrap them, spread them out so the legs will be near them as you move around in your sleep. You can chunk the bars into 1/4ths or use the bar whole. Doesn't matter what brand but the white soaps seem to work better than others. Many who have tried it for restless leg syndrome know when their soaps have been removed. /Regards, Dorothy

I do support a trip to the doctor, might the diverticulosis have any bearing on the symptoms? Doctor has his history and might see something Hubby has forgotten about. /Regards, Dorothy
