I think you'll go down a lot if you are averaging 135 and even lower. But I wouldn't want to guess and get your hopes up! But here's a chart to help you guess...
The Bernstein Hb-A1c to Average Blood Glucose Conversion Table, in mg/dl and mmol/l
Keep in mind I found a few different charts, and they had different numbers. But this chart matched up to what my doctor told me.
