The Fire Within

I am guessing that being prediabetic makes this new research particularly relevant to you? I'm not prediabetic but, having had father, uncle and grandfather all died prematurely from diabetes related problems, I'm ever on my guard. I'm hypothyroid and my endocrinologist says that my confirmed Sjogrens would account for this and all my neuro symptoms. My late father had all the same symptoms for decades - and they started well before his diabetes was discovered.
