My husband struggles with his HBA1c too. It's not too bad tho, usually between 6 and 6.5. He says the best way to keep it low, is a low-carb diet but added that staying on such a diet is very hard to do. He looked very skinny (almost too skinny) back then. He did it for 2-3 years and then said forget it. He also said "no" to using an insulin pump. He did not want to take the chance of infections or having it malfunction (he knew someone with a pump that kept breaking down). Fortunately, he's not afraid to stick himself.
