I have to agree with Kelly, since I am at the point NOW where, if it weren't for my pre-op focus, and what I learned about myself, I would be in BIG trouble. It is a necessary part of the process (IMHO).
I also agree with Mike. You can do this. I know you can. And it DOEs take focus. And it takes will. But that is what it will take later, after the honeymoon period, when hunger returns.
The very best of luck to you. Today is a new day, turn the page!
