On low carb diet seem to get good reading off metformin. Problem seems to be first reading in morning before breakfast can go up to 8. Tried reducing carbs increasing carbs and ex exercise. Seem stuck any suggestions. Meter average seems to be 7.8 over last 4 weeks. Thinking of going on one dose metformin at night booked ha1bc but can't get in till 8th July and GPS and nurse on holiday. What do you think. Grateful for any advice.
