I'll follow BHD, we use Nat. Gas and for extended peiods dropping the temp is well worth it.

I too believe in insulation, and have r-30 minimum through my NW Chicago house.
Set back or now computerized thermostats have been here since we moved in.

We have 2600 sq ft on the main level, plus 2 2 car garages (One heated, both insulated) and our year round gas bill is just breaking $42/month. We do have gas water heater, dryer and cooking included in that.
