Metformin Regular vs Metformin XR

Friends,

I am on Metformin 2X1000mg each day. I was on visit to India Metformin XR is really the one available there. It is pretty inexpensive there.

I bought the XR ones and folks there say its the most common one folks take.

Any prob in taking XR vs regurlar Metformin ?

Any benefits ?

Anything healthwise I should be concerned if I am on XR ?
