Erm, I want to be you!!
I'm the complete opposite - to put a different spin on things. I still want things I shouldn't have, I can still eat a pack of biscuits, a big bar of chocolate, a whole bag of sweets, big back of crisps and dips etc. I can still eat massive portions BUT I choose not to most of the time.
My willpower is stronger though and more often than not I don't give into the desires.
I do however, crave the good stuff when I've been away for the weekend and I also think that you unconsciously make the right choices when away, for some things, so diet drinks, skinny milk, tomato rather than cream sauces etc.
Things do change, we just change differently.
I still wish I was more like Erm though!!
