Dang Typed out a long response and it just vanished. sigh.
What you need to do is to do everything you did the FIRST time you go the SI.
Namely:
HbA1c
Doc letter- "no neuro, Renal, Kidney disease. No hypoglycemic events."
Serum Creatinine
...simultaneously with the notification of the change. The Cardiac SI is unchanged.
Since they want 90 days' stability, you are necessarily self grounded for 90 days. Send your notice of the change near the end of the 90 days, with the info, to Box 26200, OK City OK. What you are doing is actually equipping FAA to get a NEW SI for NIDDM, which will occur at the same pass as the notification.
You don't have anything else you're holding back? I HATE it when airmen don't give me the full deck.
Continue to remember, beta blockers (the "olols") for the heart are prohibited in combination with Diabetes.
