So is the Metformin controlling it or not?
Hi Falcon and welcome to the forum.
The short answer to your question is no, the metformin is not controlling it. And the result of exercise can sometimes be an increase in BS rather than a reduction!
The long answer is that metformin on its own is not supposed to control it - you are. Metformin simply helps to reduce insulin resistance so that the insulin that your body produces can work more effectively. The maximum difference that metformin can make to your average blood sugar level is estimated to be around 1.5mmol. And yours needs to come down by a lot more than that! Your fasting reading of 10mmol is about double what it should be.
The problem that most of us have is that we eat far too many carbohydrates, in fact more than your pancreas is capable of producing insulin to deal with. So we need to help things along by reducing the amount of carbs that we eat. I am not suggesting a low-carb diet (although you can try that if you want - it certainly won't do you any harm and will reduce your BS level quickly).
Why not try simply cutting down on the carbs, particularly cereals, bread, pasta, rice and potatoes. These are the starch carbs that provide almost no nutrients and simply convert in your stomach into glucose. They are actually worse for you than sugar! Instead of cereals for breakfast, try eggs (boiled, fried, poached, scrambled, omelette) with bacon or mushrooms or ham or tomato (or all of them). Switch from your usual bread to a low-carb one (like WeightWatchers or Nimble - both around half the carbs of other bread). Have half your usual amount of potatoes but more of another veg instead. If you have pasta or rice, reduce the portion by a quarter but have more of the accompaniment. You will soon see a big difference in your BS levels.
