I am Prediabetic as well. The Dr put me on Metformin and said that is getting to be the norm of prediabetics taking Metformin. To be honest, it actually makes me feel a little better to know it is controlling it and preventing it from going further. It's a low dose and I also due lower carb

I am also a pre-diabetic, I just started taken metformin as well. I find just watching what you eat and your sugar intake helps you
