If you can consistently get them into the normal range, that is regulation/tightly controlled. It is at this stage that the beta cells can be repaired. Then the hope becomes that the insulin needs become less as the pancreas is able to do it job again. Overtime...then remission.
Simmy recovered very nicely, which tells me his body now knows what normal is again.
High five to you Jim for taken such good care of him. Chin scratches for Simmy.
