Cadbury Creme Egg - I thought just one small bite wouldn't do any harm but once I had the taste of it I couldn't stop! A friend gave me some as a gift having forgotten I was diabetic. So two lessons here for me: 1) Never try 'just one small bite' and 2) Preferably have nothing in the house which could be a temptation.
Footnote: It tasted delicious but oh the guilt!
