Check your levels both immediately before and 2 hours after meals, that way you'll learn how much different foods affect them. Aim for no more than a 2 point rise id possible, any increases will show which foods have most and least impact on your BG.
The information to be gained from doing these tests is much more useful than just checking morning fasting levels, and if you take heed of your results and modify your diet accordingly then you'll have much more control over them and so over your diabetes too. Fasting levels are more under the control of your liver, but should eventually come down as your other levels improve.
