I totally want to hibernate in the winter. I'm happy to be holed up all season if I could. I do get a bit of cabin fever though and long for spring and warm weather. It's setting in already and I'm getting restless.
When I need comfort, I just opt for hot foods. Soup always does the trick. That and hot cocoa.
As for holiday carbing and weight gain... I stayed relatively Primal and still saw the scale creep up about 8 pounds. Water weight mostly I'm sure. I'm back down 4 pounds in less than a week, however, and that was going 100% Primal.
And affording the grass-fed beef. One word. "Cowpool." I went in with several others and bought beef last autumn. Should last me a few more months until it's time to buy again. You get a discount for buying bulk, typically.
