Hi Barney,
I suffered from light-headedness, dizzy, and the room spinning. Now after approx 15 months since dx, I feel like a new person.
First, my blood pressure was high. 160/100. My FBS was an 8.0. Glucose test 16.0. I was in my dizzy heights
I had intense tiredness and wanted to collapse in a heap at times, so tired.
I have cut all starches, rice, pasta, potatoes, breads/flour. No sugars for me. I eat a sm amount of Low carb fruit ie berries mainly. I find that LC is what helps correct those numbers and the body takes a while to adjust, possibly 6months at best.
Have patience, try to test with your home meter daily and see what foods will spike you. Its the best way to get control.
Good luck and you will learn a lot here from more knowledgeable members.
