"According to my doctor's office the daily blood sugar level is not as important as the HbA1C (3 month average) which should be under 6.5"

Dave, it's usual for T2 to be controlled by diet and oral medication (mine is), but I'm reliably informed that there are cases where insulin is required. Not sure what the circumstances are though. Pretty well every T2 patient I know controls their glucose level by diet/oral medication.
