We also splurged for a $30 programmable thermostat which keeps our temps changing. So far we have it set at:
58-60 from 830 pm to 430 am
63 from 430 am to 730 am
60 from 730 am to 4 pm
62 from 4 until 830 pm
And that's Monday through Friday since dh and I both work outside the house.
On the weekends:
58-60 over night
63-65 during the day
When dh and I got together he was used to how his ex kept the house at 80

so moving in with me was a shock. I liked the window in the bedroom open in the winter...

We compromised and kept the window shut but the temp about 68. When his kids came over they ALWAYS complained about how cold our house was. I bought them blanket sleepers, extra thick comforters and they still would complain

Ds arrived and didn't bat an eye at the cold, never has really. Must get that warm blood from me

Plus we cosleep so keeping warm at isn't hard. He wears wool pants with a long sleeved tshirt and slippers. We have a down comforter so we're toasty.
Getting back to dh's kids... They have learned how expensive gas prices are especially this year in 2 ways: 1) their mom moved in with her fiance and she doesn't have control of the temp 2) we told them when they're over, we can't afford to keep the house any warmer than what we have it at.
We have a new/used woodburning fireplace insert to help keep the main floor warm which we're still not sure if it will help keep gas costs down... We haven't seen a bill yet. And secondly, I bought some new/used thick wool blankets for the kids in addition to their annual blanket sleepers. I think they're getting used to being cooler
