I've been on metformin the whole time, was on insulin briefly then took Jardiance for about a month before it turned out I didn't need it, no kidney involvement.

Can you say more about how you "watch what you eat", are you doing carb counting? Is the exercise every day? Those are the two things that have really worked for me, when I cheat on either my blood glucose readings go up immediately!

Also there's always some fine tuning on the diet, discovering which foods cause the most trouble but also finding foods that seem to help! There is a lot to do managing diet and no easy reference point for most of it.

Sounds like your A1C should be great, don't know as much about the CKD to ask or tell anything.

Best wishes.
