Hi Natalie, congratulations on getting someone to listen! I was going to suggest taking someone in with you for moral support, but it sounds like you don't need this.(When pregnant and put on insulin, it took me bursting into tears for the doctors to hear my worries about non-stop hypos - tears seem to turn them back into human beings!)
I am gobsmacked that they are asking you to eat fruit whilst low carbing. As another poster suggested, I would take a good multivitamin, but a lot of veggies have higher levels of vitamins, eg red pepper has more Vit c than an orange.
Have you had a look at the Scandinavian diet? This is not low fat, but if you are willing to strike off on your own in terms of determining your diet, it might work wonders with your sugar. The book, Diabetes, No Thanks by Lars-Erik Litsfeldt, give a great overview of the diet and its effects. If you are successully low carbing, you should have no trouble sticking to this way of eating. I think I got my copy from amazon. Whilst on this way of eating, my sugars went down, I ate less overall, my skin improved as did my bleeding gums. I can't recommend it enough.
Good luck with getting your docs to treat you like a person, not a disease and with the revised approach to your meds.
