tbh, anon125, since every diabetic is different, there is no good way for us to recommend a change to medications. There are too many other variables, like other medications you're taking, conditions you may have, how you plan to expend that energy,... Then there are the variables of when you would change the meds relative to when you were eating the carbs and burning them off. In my opinion this is a question best left to your medical care team.
