Hi Leeds!!! You arent far from me, Im going over Sunday to get some stuff from Lush!!!
Now then, what you are doing isnt that un common, I'm sure I'll be corrected if I wrong, but its called "last supper syndrome" I do it every time I have a bash at SSing. I hate it and cant break the cycle.
It is your mind playing games and an automatic reaction is to eat, its being addicted to the desire to eat rather than the eating it self (Gilian Riley Overcome over eating book). If that makes sence.
Things you can do
1, Try to break that cycle, you are all set up to lose the weight, what is gonna happen by putting X Y Z is mouth, other than the diet will last longer.
2, Carry on and Dive straight in to SS, slug that water, head down and eyes on the prize.
My last bit if advice is when you near the end of your CD journey, please explore your Demons with food. Try and break the cycle of over eating, and also explore your mind. I sound like a fruit cake but believe me, its worth it x
PS, Im on my last SS, Im on Day 5, and I hope this will be my last ever time, I dont want to do this again, i want to be slim for ever x
