Glad to see you are scheduling the blood tests - it would be good to know if either of those are what are causing the insulin resistance.
I didn't get the earlier tag. We don't start R unless we know what we are dealing with, be it ketones or a secondary condition. And with a secondary condition, lots of people manage it well without R. So it's situation dependent. I didn't start using R until a few years in - mostly because there wasn't a regular poster who was experienced with it and available to help when needed. R is a powerful but but potentially dangerous tool. You need to learn when to, and most important, when not to use it.
