Look up Dr Ken Berry On Youtube. He Will walk you thru how to reverse it. I followed his advice and thousands of others and got off meds. My A1C stays around 5.5-5.7 now with no meds. You will have to go low carb Keto to do it though.
My dr told me to come off my meds I was a 5.5 finally. Low carb is a lifestyle not a diet and it isn’t easy. August 14 will be 5 years for me.
