I just took a look at your old messages to get up to speed. Are you using U-100 syringes or U-40?
My Tucker is stuck on insulin because he gets daily steroids, but I have him on really low carb food and he gets micro dosing using the U-100 syringes. If it wasn't for the steroids I think he would be off insulin completely!
He is getting 0.3 units AM and PM.
So, you could try two things - get her off the DM and on low carb completely and see what happens. On the right food she may not need insulin.
Or, you can switch to U-100 and use micro doses - instead of a U-40 syringe going by 0.25, 0.5, 0.75 units you would go by 0.2 or even 0.1 if needed. There is a conversion file somewhere on this site
I need to check but I believe less than 100 for 14 consecutive days equals remission.
