It might not be diabetes that caused your cyst. You probably just have a really good Doc who is covering all the possibilities.
When I was a nanny for a young child with diabetes, I p.rick tested myself and the reading was hug, over 15. Because I'd just been rolling out cookie dough with my fingers. (Was a recipe from Meredith McCarty's Naturally Sweet - check it out, would fit in really well with your eating plan. It's got a lot of ideas for sweet things from less refined sources)

Fingers crossed for you!!
