Thats really strange, I came on to start a post on the Cambridge Diet. I started taking the milkshake and soups two weeks ago and have dropped a good few pounds but have also noticed I have improved the amount of sleep and my energy levels are high( which hasn't happened for a long time with PN). I hadn't thought about getting the correct vitamins and minerals. I am like you in that I have had every test and still ideopathic.
