I have sometime wondered if my feet gets a sort of a crawling restless sensation under my feet everytime I eat too much of sweet the things., such as chocolate in the evenings or late night before bed time. Its really irritating. Feel I need to constant move my leg. Could be down to too much sugar in thd blood or cortisol or insulin. Not sure maybe its a sign of boring to type B diabetic or something. It doesn't happen often but seems to have more if an affect on me since I stop exercising. Im not over weight or fat at all really and don't eat too much refined sugars or chocolates etc.
