Why do you HAVE to eat Easter Eggs? Either tell them about the diet or say you'll have it later. You don't HAVE to eat chocolate. Are they going to sit down and not let you leave til you've eaten chocolate? It sounds as if you're trying to justify it. On a diet like this you're going to face problems like this over and over you can't give in and eat every time. Just thank them very much and hang on to it. Believe me youll feel so much better for resisting it
Restart tomorrow as planned but do it properly otherwise there'll always be a reason not to
