Wear a robe, long sleeve t shirt and long socks, even to bed. I would throw the robe over my blanket. We all have electric blankets, makes a huge difference. I bake more dinners in the winter, turn off the oven and open the oven door when the meal is cooked. It heats up the house real nice. Don't hang around your dad when he smokes anything. Smoke in your body is bad for your health. Eat more iron rich foods, like beans, liver, chili.
