With minor hyperinsulinism and related hypoglycemia, how long does the onset of type 2 diebetes normally occur?

I have very minor hyperinsulinism, with resulting hypoglycemia. I am living an Atkins diet, with occasional use of alcohol, and just a few cups of coffee per day. How long until I hit the point of type 2 diabetes. This is a very important question, because with my career, diabetes would basically end it. Thanks!
