I've been getting so cold I've brought a blanket to work to cover my legs up! It was annoying me quite a lot until I realised that previously I wasn't cold because I had a not insignificant amount of blubber covering me up. As blubber goes, Claire gets cold. And all the super thin people in my office are also complaining, so I feel like a cool (cold?) kid now.
Hot water bottles, wearing sweatshirt and trousers in bed, going to bed rather early all working for me. Primark are selling legwarmers at £2 or so the pair - may buy some of those for the tube journey home! But think of it this way - we may be extra cold when we are doing this in the winter, but we are also not subject to the barbecue tasting tempting.
