Tegan, you couldn't be suffering from an underactive thyroid if you are feeling the cold more than you were, could you? It's the sort of thing that creeps up on you but is easily diagnosed (or excluded) with a simple blood test, and if it is a problem, is easily treated.
We have our heating set at Auto all the time, which means that it comes on when the kitchen/living room temperature falls too low, but we also have room thermostats so that the bedroom is about 17-18º, the sitting room is about 20º and the spare bedroom is 15º unless someone we like comes to stay
. We did try having it on timed, but it kept coming on when it wanted to anyway, so it's been cheaper to leave it to do what it wants. We tried leaving it on all the time as well, but were boiling so stopped that one very quickly.
granjura, I agree - what's the point in doing all that knitting if you never wear your winter jumpers? I hate the way shops put their staff into light-weight clothes all year round and then turn up the heat so that customers who are dressed for the cold outside feel uncomfortable when they come in. I have complained several times, usually in M&S, that I am too hot to think about buying anything, but to no avail.
