As I understand Type II you produce inadequate insulin to deal with the carbs in your diet so you top it up. I also assume you have become type II over time. Eating this way will reduce your requirement for insulin as you will be processing a lot less carbohydrate depending on how much you are eatiing now of course.
My guess would be that you will need to use less, but you'll need to check that out by blood testing (which I would assume you would do anyway now?). If you use too much insulin you will run the risk of a hypo (which I'm sure you know), so you certainly need to be cautious as you start the PB. Lots of people here find they no longer require insulin and consider they have reversed their Type II status now they eat low carb.
Hope that helps.
