I had them too. Calf stretching exercises, warm legs, warm feet, always wearing slippers and even bed socks at night and they went as blood sugars went down. I used to get bad cramps too. Pamper your legs and feet and keep them warm. It's the cold, it sneaks up on you. Don't walk bare foot around the house or even just in stocking feet. A good regular massage with a long handled brush in warm soapy water and your feet won't nag you anymore. Just look after them.
