Harvest moon have you tried hot water bottle up ya jumper ? Seriously I do it on the really cold nights instead of putting heating on it's cheaper. I live in a house though I'm not lucky enough to be on the land I can't afford a van and I'm looking after my mum at the moment but I dream of packing up and roaming one day. So my heating bills can be quite high if I put the radiators on and I can't see the point in heating rooms I don't use so I leave the heating off as much as possible or unless I get visitors then I put it on for them. Did you really cry with cold? That breaks my heart - I have a spare duvet I can send you if it will help. If I lived closer I'd drop them round but I',m in Midlands.
