@michita Ive never had my consultant ask me what I eat or how many carbs I have (apart from very soon after diagnosis when I was on fixed doses). She tends to look at my results - blood tests, eyes, weight, etc etc, and that's what we talk about.
From what you've said - about you wanting insulin but not being given it- I can see why you had to discuss diet then, but if your results are OK and your weights ok, then you might find its not even mentioned.
However, if the consultant does bring up your hospital admission, I'd take the opportunity to push for answers as to what was behind that.
