Hi S.sollis, I would advise you to treat your healthcare team as just one string to your bow. Remember, our taxes pay their salaries, they work for us. I think that a lot of diabetes doctors and nurses (not all though) treat their patients as misbehaving children. Therefore, when someone like you comes along, they react the same. When I say someone like you, I mean someone who is actively engaging in looking to manage their diabetes.
You have already used the magic words in your previous comments- low carb. In my opinion, it's the holy grail of diabetes management, whether type 1 or type 2. I would advise you to build on the solid foundation you have set and research further. Read Dr Richard Bernstein's complete diabetes solution. The title really is no understatement. I have never come across a more in depth diabetes resource. The man has lived with type 1 himself for most of his life. He is now in his 80s, so he really does know what he's doing. Dr Troy Stapleton on YouTube is another good port of call.
www.lowcarbdiabetic.co.uk is great for recipes too.
My own relationship with my health team is this: I have politely told them that I am going to eat a low carbohydrate diet, and that I won't be dissuaded from this under any circumstances. Thankfully, my specialist is open to working with me, providing I show good results regarding my blood sugars. It goes against what she advises, but she is willing to work with the evidence, which she has been impressed with so far. If you were to adopt low carbohydrate fully, your health team will probably try to dissuade you. If it makes your blood sugars well controlled, make sure you are testing often so you have hard data to back you up. And regarding insulin doses, don't be afraid to experiment. However, make small changes gradually and again, test regularly to avoid the risk of undetected hypos.
Hope that helps, and best of luck.
