Is Winter Over Yet?

I know, I know - it hasn't even officially started yet. But I get so cold. Whenever I get really tired (which is most of the time) my body temp just drops & I freeze. Last week I got half an hour of sleep from Monday evening - Tuesday midnight. I was so flippin' cold I spent the whole night at work Tues. wearing my hoodie, coat, scarf & gloves. The gloves came off when I passed meds. They were in the way. I tried to keep my house thermostat set at 68 degrees but I spent the whole time shivering. It's at 71-72 now and I still want to turn it up more. Oh well.
