I used to have restless leg syndrome. It would always get really bad when I'd go to bed an night (naturally), and it was awful. I would rub, massage, or even punch my legs just to get rid of the feeling. I don't seem to get it any more but I don't know why. Maybe because I have a lot less anxiety in my life or because I was on some medication at that time that caused it. In the past I've been on medications where because of side effects -and the shrinks pushing the drugs being heartless quacks- I could not stop moving or pacing around for hours until my legs would cramp up and I'd be forced to sit down, but it wouldn't let me. People didn't understand or care except maybe my mom, because she would hear me pacing around in the middle of the night from her bedroom and sometimes I'd even go out walking at that hour.
