Im also scared to eat anything non CD and that stops me straying. I can honestly say that I dont feel tempted to eat anything 'forbidden'. The other day I had a terrible arugment with a friend which under normal circumstances would have = sugar binge! I didnt feel like that at all.
I have determination and stamina to stay 100% but Im sure if I do even a small 'cheat' that I wont be able to stop. Then when I go for a weigh in, if I lose weight or even stay the same after being 'naughty' then I will say, okay nothing happened, maybe I'll have a treat and you know the rest.....!
Its 100% all the way and its my fear that keeps me going!
