Great news
@BadgerPaul.
I will give you my own experience here, though, just to give you a wee 'alert'. I got my HBA1c down to 40 a couple of times in the first - 5 years I think it is? post diagnosis. Maybe 6 or 7? And was in the prediabetes zone for that time. In some remission circles, this is called imcomplete remission.
A big part of remission, according to my understanding, is the passage of time. And No 'anti diabetic' meds, naturally.
Then, even on a low-carb diet, and then with IFing, my blood glucose became very susceptible to rising quite dramatically with various changes, to such an extent I must face the probable fact that I have some serious longterm IR damage in my blood glucose system somewhere. (I have been normal weighted since low carbing, nearly a decade now, so it's not now fat cell related, at least that can bring about remission.) Due to my extensive bio marker/BG tracking I believe I know where, or have a pretty good idea, and am currently in the process of trying to convince my great longterm city doc to let me choose my meds based on that info. (So far, not working.)
Anyway - because type two is metabolic, it is very sensitive to switching treatments, due to something called the hormesis effect, is my understanding. And so much to do with type two is at cellular level, cells can respond quite dramatically to hormetic stress. For me, it goes the other way too, easily alas.
Anyway, just posing a wee 'alert' here.
