First of all Em, Congratz, you look great! Your hard work and perseverance has paid off. I can relate to several things you said also. You are doing a great job with the workouts, something I also make sure to do (4-5X weekly mostly cardio, some arm curls/weights and sit ups). I have also never been a slave to the scale...until recently since I am now in maintenance. I am 10 months out (6/14/17).
I think you may need to go back to the basics of concentrating on getting the protein/fluids in first. I do find the more carbs that I eat, the more that I want. Until you get to what you feel is your ideal "goal weight", it is really important to stick to your plan. Though you worked out and ate healthy pre-surgery, you now have an incredible tool to use to your advantage. Work the tool girlie!
