Turn down the heat and put on an extra layer of clothing.
No need to keep your heat cranked and pay for it later. As the cold winter sets in here in Ontario, I often turn down the heat and wear a down vest in the evenings and sometimes cover my legs with a blanket as I watch TV and unwind. The house is not cold by any means but it is comfortable and an extra layer keeps me toasty. And there is no need to go and spend lots of money on a big sweater or vest, I found both my vests for a couple of bucks at second hand clothing stores.
