First hurdle over, first goal achieved, first point proved to yourself and others - you do have the willpower to do this, and you can do it if you really want it.
I am not 810 either, I am SS also, but I think any diet where you suddenly limit yourself causes your brain to play tricks on you and torment you. How many times have you dieted in the past and said something like "I will not have pasties, potatoes, bread, or pizza". Probably a really good way to control your carb intake and lose weight, but what is one of the first things you start craving? ...... a cornish pastie, a chip butty, or a pizza ...... well you do if you are anything like me anyway!!
Just stick with it and it DOES get easier, believe me. You get into a routine, and after a while it becomes a habit. The good thing is that it is a habit that will help you for the rest of your life as when you have done this for a while you learn that the body does not NEED the amount of food we shovel into it ... it can survive quite happily on significantly less, and that is one of the best learnings that comes out of this diet. Once you have that it is simply a matter of remembering in times of stress!!
