Over here in North of England winter is fast approaching - if not here already. The last of the leaves are falling and the morning frost is starting. Now I once read we have natural animal instincts to hibernate.

I usually suffer from s.a.d (seasonal affective disorder) in the winter anyway but now I'm finding I can not stay awake. I can sleep 12 hours and struggle to wake up, when I got up I find it hard to stay awake and I'm eating very little. I went through a period of eating loads now I've just started eating hardly anything.

So I'm curious does anyone else feel the need to just hibernate in winter?
