Well done - I wish I could match your results!
I have been T1 for over 60 years now - still here - no complications - so must have been doing something right for a long time!
As for Diabetic specialist nurses - I now refuse to talk to any at my surgery because after a visit lots of years back I was told to stop testing BG so that they could reduce the quantity of test strips and insulin as (QUOTE) it would save the surgery prescription money (COSTS).
I stood up and told her not to be such an idiot and walked out. *I was followed in to the main reception area and then lectured about the fact she new more about my condition than I did and that I should follow instructions. My reaction was to inform her that she was ignorant and was a danger to patients then really swore at her telling her to F##k off - go back to training so she could learn what a total pratt she was. A couple of people in the waiting area made appreciative comments and others complained to the surgery about the language which I used.
2 weeks later I received a letter informing me that if I ever expressed my feelings so bluntly ever again I would be removed from the practise.
My advice , for what its worth, Trust your hospital consultant when he explains the reason for an instruction, use a similar but cautious approach to Hospital Diabetic Clinic Nurses and Local GP's but surgery DSN's must be treated with extreme scientism when you get an instruction which is wrong (like the info you were given) just refuse to have any further contact with them and if they ask why just tell them you do not want to be given any more incorrect information.
Do not loose your rag like I did!
