I've decided to sort myself out and 3 weeks ago cut out all chocolate, cake, biscuits and bread as a snack (so ok as a sandwich lunch, not ok to have random slices of toast through boredom eating).
I have had sweet food as in fruit and had a small cup of hot chocolate so not sugar free. I will be having a slice of cake for my child's birthday next week.
My partner has some chocolate hobnobs and a small piece had broken off so I thought sod it, it's too small to make a difference - it tasted grim. Just pure fake sugar. I ate them very happily just a month ago. Can tastes change that quickly?
