I really sympathise - it's going to be my first year hopefully saying no to any eggs.
The worst bit was going into Sainsbury's today and having to buy for friends and family, and will admit that I nearly caved! I'm trying to be positive, though - I can still celebrate Easter. I'm visiting my parents today for a week, and we will have lots of nice meals, that my mum has very kindly offered to cook according to plan, and I'm thinking of doing an Easter egg hunt around the garden for my goddaughter and friend's children. I love them as if they were my own, so seeing the smiles on their faces will be more than worth it, and hiding them around the garden will be fun.
How about treating yourself to something nice that isn't chocolate, to congratulate yourself on your tremendous willpower? Maybe some nice smellies (I love Lush bath bombs!), or giving yourself a treat at each milestone? I buy an item of clothing at each half stone, and the realisation that I have gone down at least a dress size (two in some places) since starting gives me a reason to carry on.
Good luck - you can do it! X
