What i found was that as i worked on the timing and carb counting, i gradually became able to bring my post-meal blood sugars down, first below 10.0 as Scheiner recommends, and now usually below 7.8. But if my post-meal reading is really low, say in the 5s, that is too low, and it means I'm probably on the way to a hypo, so I eat a bit more. I did it bit by bit. Now most of the time I'm in range.
Have you had any other checks at the diabetic clinic? T2s can have thyroid problems, vitamin D shortages, and also B12. I think your GP could probably order tests for all those. B vitamins may help if you think you may have started developing nerve damage. And exercise because it has an anti-inflammatory effect.
