I don't understand threads like this. To me, this is like asking "how much pepper do you use on your eggs? Maybe I should reconsider how much pepper I use on my eggs based on your inputs?"
So I'll answer in a general way first - for winter, we set the heat as low as we can and still feel reasonably comfortable, balancing that with a desire to save money and reduce the environmental impacts of setting it higher.
I pretty much do not pay attention to the numbers. I use comfort as a guide.
But for reference, we turn it down to ~ 58~60 at night. Once you are under the covers and warm, the air temperature isn't much of a factor, and it takes hours for the house to lose a few degrees. We are already asleep.
In the AM, I turn it up to take off the chill, and adjust it when I feel reasonably comfortable. I wear socks and slippers, long pants, an undershirt, shirt and sweater (layers are key). Often, I feel fine at ~ 62~64. If I'm actively working on something, that might feel too warm. If I'm not active, I might turn it higher, might not. Depends on how I feel.
By dinner, we turn it up, maybe 68 for the rest of the evening.
A lot depends on your heat type. With forced-air and Natural Gas, the house feels warmer in minutes, as the warm air circulates. Yet, it takes hours to cool appreciably, due to thermal mass.
When we go to MIL's, the heat is stifling. I need to dress like summertime in the middle of winter. I may start taking a fan. But that is what she needs to be comfortable.
