Trim your nails. My husband destroys bedsheets, especially, the fitted one, because of his tossing and turning due to restless leg syndrome. When tested for it (he didn’t believe he had it), he asked the sleep technician if he had it because his wife was making him do a sleep study to determine it. The sleep technician told him that he would receive a follow-up with his dr and that he really shouldn't discuss it with him. When my husband pressed him further and asked if he moved around at all, the sleep technician said, “Moving around? You’re running a fuck**g marathon, dude!”
