blood glucose imbalance - advice

[mirabel]

I have a blood glucose imbalance and have been using a blood glucose monitor for the last 2 weeks - it shows a fasting blood glucose from 3.8 to 6.7 and 2hr post meal from 4.8 to 8.5. My fasting blood taken by GP was normal recently. I have been aware of a problem for last 5 years when I lost some vision in my right eye and was diagnosed with a form of lupus. I also have a very strong family history of diabetes. In December I lost more vision in my left eye and I may not be able to drive again. I am a vegetarian and already restrict my carbohydrates and use brown rice and other low GI products including agave. I am losing about 2lbs per week weight and try to exercise when I can. I am going to see my GP next week to discuss the blood glucose imbalance and to see what he suggests. Does anyone else have this type of problem or any suggestions to help?
