Wide-O, thanks for the input. My diet was few if any sweets and only allowed myself a teaspoon of sugar in my morning coffee. I like my fresh fruits but even cut back and I stopped drinking my fruit juices. I love my pasta but gave that up as well as potatoes and white bread and rice. The weight loss was a real issue so now I am doing everything in moderation. I have cut back on my carbs but won't deprive myself either.

I was aware that Metformin can deplete the body of B-12 and called this to my doctor's attention. She was unaware of that fact but said we could periodically test the B-12 levels. Currently they are good. After careful consideration I believe this to be the best path going forward.
