Hello and welcome to the forum,
As
@Resurgam pointed out, Glucophage (same as Metformin) does not directly lower blood glucose.
Like Resurgam, I "reversed" my Type 2 diabetes by adopting a "low carbohydrate" diet (see signature below). By "reversed" I mean that our blood glucose levels are "non-diabetic." We still have the disease, but if we keep those levels low, we have a much better chance of avoiding the complications of the disease.
If you are only taking Glucophage, and no other diabetes drugs, it should be safe to try the "low carb" diet if you are interested. "Carbohydrates" are much more than just "sugar" and include many common foods, including for instance bread, rice, pasta, potatos....

I believe you are located in Islamabad, Pakistan. In some countries, including many Western ones, the "low carb" option is not actively advocated by doctors and other medical professionals. So don't necessarily expect much support from your doctors if you try this "diet" route to controlling Type 2 diabetes.
This forum is a great place for help and support.
