I have been setting it at 68 most of the winter, to try and keep the heating bill down, but I swear, this deep freeze weather has chilled me to my bones. I just can't get warm. At 68, I was wearing big heavy sweater, and a blanket over my lap just to watch TV. A few days ago, I broke down and "cranked" it up to 70. I wish my house had a fireplace. If it did, I'd be spending most my time camped out in front of it.
To those of you who can handle it in the low 60's, more power to you. I'd need a snowsuit to keep warm at that temperature!
