Hi lesley,
I think your diet needs tweaking IMHO.
We all have to cut our carbohydrates by some amount and testing really is the answer. Bread, potatoes, rice, pasta and cereals are the main culprits and we all have an individual response. Some prefer to cut these out altogether. Have the sunday roast if you enjoy it as life willl get terribly boring if you don't have a treat to look forward to.
Try substituting the white bread with some granary, stoneground or soya and linseed and this may give you better readings. Keep away from fruit juices and processed foods
Try and fit isn some moderate exercise most days. 30 minutes is recommended. You can do 2x15 minutes or even 3x10 minutes.
Above all, keep a food diary and test, test and test again. It is a sad fact that most Type 2's are given bad advice and left to get on with it so it has to be us that manages this disease.
I am still puzzled why your fasting levels are so low? Any ideas?
Hope this helps,
Catherine.
