Yes, i think you are correct , it does do the above. Also, research last year, and research reported recently re type ones, shows a cardioprotective effect (i think this was found for type 2s earlier), i am not sure how this effect happens or whether it is just due to reduction of insulin resistance. maybe these studies are what Dillinger is referring to. At the moment, at least in the NHS, i have been told that only type ones in certain categories are prescribed it - i am not being prescribed it, despite asking about it, even though i am older and in a risk group, i am just too insulin sensitive. Insulin sensitivity, as the original OP has found, is not always easy, and dealing with it can be quite challenging.
