Hello there.
There is no doubt that it's great you have a diabetes nurse you obviously feel you can work with.
When I was newly diagnosed, I was literally a couple of weeks away from leaving on an overseas trip scheduled, at that point, to last 9 months, so it was all rather inconvenient! I was similarly advised about a meter, but I went ahead and acquired one anyway. (Always the rebel, me. 🙂 ) My rationale was that by using my meter to measure my reaction to everything I ate or drank, I would soon begin to understand how I could manage things to stay healthy and improve as much as I could.
To say testing was enlightening would be a bit like saying Hurricane Katrina was a bit breezy. Whilst I am certain my diabetes nurse, in the brief meeting I had with her, believed that wholemeal bread, unsweetened cereals and wholemeal pasta would be fine for me, the meter readings, shortly after eating, screamed a very different story. Having learned what "good numbers" were I rapidly realised I'd be better avoiding the wholemeal bread, unsweetened cereals and wholemeal pasta, at least for the time being.
When I returned, briefly to UK for a review, four months post-diagnosis, I had reduced my diagnostic HbA1c test score from 73 to 37, and in the intervening period to date, my HbA1c has never been above 34. Bearing in mind the diagnostic threshold is 48, I think you will appreciate the change.
In that four months (and to date) the heftiest weapon in my armoury was everything I ate and drank, closely followed by my trusty blood glucose meter, giving me immediate feedback on my progress.
I do urge you to acquire a meter and strips if you can. If your medics won't sponsor testing, then I urge you to consider buying the supplies yourself. For me, it was a life changing purchase.
