I understand how you feel, diana. I was told early on because of my family history, hypoglycemia can be a precursor to diabetes.
I'm concerned, too, since i've relapsed in august and my symptoms were so severe. But like stan said, I believe you would have to consistently eat poorly for hypoglycemia to turn into diabetes.
Case-in-point: my brother never ate right, exhibited hypoglycemic tendencies and he's a diabetic at 38.
I view my concerns as just a way to keep myself in "check". If I don't "cheat", it won't happen. :)
