So. All day I have tried to eat no carb. No breakfast. Lunch salad (rocket pepper tomato onion) good ham and some cheddar. Dinner green beans mange tout and steak pie without pastry. Blood glucose now 16. Any ideas why? Been keeping to carb less than 20 last couple of weeks. Why won't my blood glucose come down? Im on metformin 500 twice daily. Any suggestions? welcome.
