Hi again Chrissie,
Testing regularly to see which foods send your blood glucose figures high is a good idea. Losing weight will help also.
However, as far as I'm concerned it's the cutting back dramatically on the starchy carbohydrates - i.e. cereals, bread, potatoes, rice and pasta etc that will give you the quickest and biggest improvement in your blood glucose levels.
People get some very big improvements in their HbA1c readings by taking such action.
In my opinion, that's a much better idea than going down the medication route and progression to injecting insulin.
Good luck - John
