Do you start slow with one dose a day? Do you typically start mealtime insulin at the same time? Though my recent A1c was excellent at 5.6 the doctor stopped the sulfa I was taking saying that it was no longer working, and told me I was at the max with the other drugs and there was nowhere else to go but the insulin route.
A year ago my A1c went way back up so I started yet another med. That has proved very successful I am just looking toward the future.
