The most common cause of leg and foot cramps is calcium deficiency which is why people who are lactose intolerant are prone to this in older age. Given that you were anorexic, you may have problems with calcium and iron deficiencies.
You may want to talk to your doctor about this because if your leg cramps are due to a calcium deficiency, you may want to find ways to alleviate that problem because Osteoporosis is also caused by low calcium mostly in post menopausal women.
