I'm not sure I can help directly as all my experience is T1 with insulin - I can give you chapter and verse on that. All I can say s that you need to do the research yourself into how your body now reacts to exercise, whcih means testing regularly before, during and after, say every 30 mins of exercise. You also need to do the research yourself into how your meds work and how they interact with exercise.
Be prepared for exercise induced hypos, and be prepared to not recognise them as the symptoms will get masked by the exercise. But test, test, test and always carry both QA and slow release carbs.
Out of interest how come you're not straight onto insulin as a T1?
