My guess is that either remedy will probably work. If your adding bolus insulin to cover the mealtime carbs that your pancreas is unable to handle I think that will work. Or you can add basal insulin and allow you pancreas to rest and prepare itself in advance.
Of course you could require both but I don't see that need in you case. Your numbers have crept up but they are not over the top at this time. I think it's great that you are taking measures now instead of waiting till it's (diabetes)a full blown monster that is even harder to tame.
