I know exactly what you mean re testing and their policy of it not being necessary, I'm the same. Crazy.tbh once yearly check ups suit me fine and I still regularly test (self funded as my DN says I don't need to test but that's another topic ...) and if I noticed a huge increase then I would get in touch with DN for advice but again tbh I feel I know more about my condition than her because if I had relied on her advice I would not be in remission which was something I have achieved on my own ...
I too feel more clued up about my diabetes but my problem is when it goes off the rails I struggle to get help to sort it out
