Sugars less than 70 mg/dl? For most people that's the edge of hypoglycemia. Do you have a reason for that number? Are you diabetic? Is that a number that your doctor is happy with?

When they were doing a research study on the advisability of getting diabetics down to an A1c of 6% they actually had to stop the study because of excess mortality among the participants. They may try again now that continuous glucose monitors are available to help manage the risks.
