We have a programmable thermostat and set it to switch down to 55 degrees at 11:30pm and come back up to 65 at 6:30am. The neat thing is we didn't even notice the lower temp at night.
The power bill dropped quite a bit.
EDIT - that was last winter. So far here in Sunny CA it hasn't gotten too cold yet.
