3. Her blood sugars of 300 are too high for waking up after fasting all night.

If her blood sugars are above 600 after eating again that is too high. Both of those are particularly troubling if she has started a metformin regimen and makes me suspicious that her body is not producing any insulin whatsoever. It is not a surprise that she feels exhausted and her weight loss may also be attributed to her high blood glucose levels.

As far as diet is concerned she should reduce her intake of carbohyrdrates (including bread and pasta) and starches since they will be converted to glucose. She should also try to get some exercise although that may be difficult with the fatigue.
