@Wady69 I started out with an A1c of 9.9% (84.7 mmol/mol I think) early last year. Last A1c was 5.4% (35.5 mmol/mol I think; not sure if I'm using the conversion calculator correctly). I accomplished this with the LCHF diet and walking alone, though I took some nutritional supplements too.
To medicate or not? That's a highly individual decision. If I took medication, I know I'd be naughty. But that's not true for others. Just me.
Congrats on your achievement. 100 to 43 in 4 months is impressive with or without medication!
