Hi, I am sorry you are having such a rough time.
Tell what were your readings before this major trauma (as you describe it) that involves your kidneys?
Also do you have any dietary restrictions as a result, for example do you have to be salt free or limit the amount of protein that you are taking, etc?
Normally when sugars are so high a few days of no carbs bring them down pretty fast and then continue on very low carb to maintain, but this might not be suitable for you due to kidney problems?
I note that you ask not to tell you what to eat as you have been diabetic for 10 years, it is good that you are confident in handling your condition, but we live and learn something new all the time, so maybe we should all keep an open mind?
I hope you get sorted and start to feel better soon.
Karen
