Hope you find it easier on the tum, and that it helps you manage your glucose levels.
It’s worth remembering that metformin doesn’t work directly on meals, it helps the metabolism ‘in the background’ by improving insulin sensitivity and helping to reduce glucose output from the liver. As such adjustments you are making to your diet are really important in terms of your glucose management. Eg reducing your overall carbohydrate intake (not just sugars) to a level which your metabolism can cope with.
