68 in the day and 58 at night. I admit when it's really cold (like less than 20) I jack the heat up to 70 for a bit. My house is well insulated, new windows, roof etc, so our gas usage has been "as low as the most frugal customers in our neighborhood" that the company sends us stats on.
I don't mind the cold when I am outside dressed for it, but I hate being cold in my house. I guess it comes from living in the Sunbelt for so long. Our energy usage is very low compared to most I know, so it's fine with me.
