I think you need to take some advice on that. Might be wiser to go carefully with the carb reduction - and monitor with your meter before and after meals.
What I’d find difficult in those circumstances is that many doctors will either not approve of or know little about a low carb way of eating, so may discourage it. I think also there were questions about your kidney and possible contra-indications with the medication you’ve been prescribed? Perhaps start with that discussion? You might be able to get an alternative or to agree to try using dietary change for a few months pending the next HbA1c?
Your meter would give you advance warning if the changes weren’t helping.
