As you have only just begun to take it seriously again you have nothing with which to gauge your present situation - you might well be a long way down from your highest readings. Just keep on testing and avoiding high carb foods and with any luck you'll begin to see lower numbers.
As a type two carbs are never going to be a good option, and like me you might well need to stick to a low carb diet for life if you want to avoid the consequences of being carb intolerant. It does mean that I have the energy to visit my grandchildren which is something I am thankful for.
