Usual Muppet docs, all the time your beta cells stay in a state of high glucose they get damaged.
Ever wonder why T2 is seen as progressive chronic ?
Doctors never attack the cause, only the symptom.
You've possibly won the lottery of life, whatever changes you made was enough to stop progression, amazing potential for future remission I'd say. Well done. But lets get you <48 at least.
The drugs are often a stop-gap measure until you require more, diet & exercise is the real way to go, especially with a low diagnostic level.
Carbs make your bloods go up & down, have you ever researched low carb & understand it's not just sugar ?
Bread, pasta, rice, fruit, potatoes need to go on the naughty list.
You have a meter, maybe a CGM would be worthwhile purchase.
You are in a zone where could reign this in, I will hope to see your update soon
