You have my full admiration. Your story is inspirational, although you now have to keep it up! I am certain you will because you seem highly motivated. Your doctor probably thinks your HbA1c is too low because you were on insulin, and anyone on insulin can have low HbA1cs if they are hypo much of the time. Now you are not on insulin, this isn't an issue, so your HbA1c is not too low. Doctor is wrong! Well done, wonderful achievement.
