In the US it is by prescription only, and my doc gave Metformin to me when I tested positive for insulin resistance. Some docs aren't as willing to prescribe it, others are.
There are lower carb versions of most breads and such. I eat sugar free chocolates and sugar free icecream, but I don't know if that is available in your area. It is a whole new way of eating, but it feels so good when you start loosing and realize the diet is working best with your body
