I'm still feeling better than I've felt for a while and I can't quite pin down why - unless it's all down to cod liver oil - - which I doubt - - but I've been taking a cod liver oil capsule every day and also a calcium tablet, for about a week now.
Today I ate:
four small slices of cinnamon and raisin bread with butter
chicken kiev with butter inside (obviously) with new potatoes and peas and sweetcorn
blueberries and a small dob of half-fat ice-cream
Verdict - - perhaps too much sugar - those blueberries are very good for you but high in sugar. Last time I had blueberries my blood sugar soared astronomically. This time I've solved the problem by not checking it. Oops.
