mine just asked me generalized questions, I was nervous too! he asked me about my goals and if I had support, asked me to explain the procedure to him and then some random family questions.
I think its just to make sure you know this isn't easy!
I am new here too! my first post as well...I had the same issue with my preop diet it was easy at first and then I cheated and ka boom! I wanted everything in sight! I don't offer much advice only just to stick to it! it will all be worth it in the end when you are recovering and it does get easier after the surgery (it did for me anyway) I literally wasn't hungry for anything, I am only 2 weeks post op and just now am starting to feel hungry again...
you can do this! don't let these little things set you back!
