I have surgery on December 4. I have been "watching" what I eat since I saw doctor for first consult on Nov 6. I feel the same way you do now, BUT I have done this 36 plus times in the past and every time I would gain all the weight back plus more. So frustrating!!
I hope after surgery the "need" to eat is diminished ALOT. It seems like all I do is think about food, while I am eating my lunch I am thinking what I am going to have for dinner.
