If you don't start diabetic meds you can die of a heart attack, stroke, kidney failure, liver failure or even pancreatic cancer to mention a few, in short order. The choice is your's, but if you continue to let your blood sugar run high even while you are trying alternative methods, you are simply entertaining silent damage to all sorts of things in your body.
Me? I'd start the diabetic meds and then try to lose some weight and adjust to a lifestyle that might be able to stave off the disease! There is no quick "non medication" solution to get you back under control. There are lots of things you can do to ultimately lower or possibly eliminate medication from your regimin, but for now, the MOST IMPORTANT thing is to get those numbers down!!! and it JUST ISN"T GOING TO HAPPEN without some chemical help. Sorry.
