Help me understand what happened to me

This may get long.

I was an insulin addict. I was shooting up 100 R&N-Type combined in the AM. Then 100 R Type in the 6 o’clock zone, and 100R&N combined at bedtime. Always had great A1C’s

I was in hospital a week ago for hypotentsion and bradycardia due to renal failure. I was given insulin as I should have been between 1-5 units of r before meals (renal diet) and 3-4 on N in the a.m.

I got reasonable good readings highest 192 after a meal and as low as 120’s as well. I have been very strict about diet since leaving with much improved kidney function. I was also taken off a lot of antihypertensives atenolol and diovan and my furosemide was cut back 75%.

I am also keeping the insulin as at the hospital.

I am curious why I didn’t od from so much of the stuff. I ate like a horse and didn’t regulate diet wwhich explains why I was 300 pounds with swell a1c’s….I have resolved to come clean about this, as if I were fooling anyone to begin with, but curious what you folks might think.
