I think I have got it. The symptoms are making sense. Fortunately it's very warm even when it's cloudy so we are getting around a bit. We drove over to two of our favourite small villages both with marinas and much like St Mawes. It was warm enough to sit outside for lunch and all the shops have massive sales at the moment so everywhere we go there are temptations. So far we have resisted them but it's only a matter of time in my weakened condition.
