You obviously have a fighting spirit so you can do this.
Just a thought. Maybe return to post op eating. This would help to withdraw from the sweets and carbs. Lots of Protein shakes, Soup, etc. (mushie stage)
I remember once when I was trying to withdraw from sugar I decided everytime I wanted to pig out I would take a hot bubble bath and read magazines or go shopping.(nothing like spending your whole night in the bathtub!!!! Water gets cold, drain, run more hot water, drain, run more hot water, you get the picture) You do what you have to do to get past it.
