Studymum I got achy and restless legs a lot and the only thing I found that helped was to get up and physically stomp around the house for a few minutes to get the blood flowing. That plus some calf stretches - so stand facing towards a wall, put your hands on the wall and take one leg back with your heel to the floor so you get a nice stretch. Then swap legs. Worked a treat for me to get them to settle down enough so I could finally nod off to sleep!
