Well done Possum,if you aren't eating sugar products your blood sugars will come down most certainly,that's what I did and I halved my sugar levels.
You are better not to go on insulin,the insulin makes you ravenous and you will want to eat everything in sight all day long.When I went on insulin I gained 42 pounds.
My sugar levels weren't brought down by insulin cos I was craving foods and eating them the blood sugar levels stayed sky high.It was the worse thing I coud do to go on insulin.
