Newly Diagnosed

Hi

I was recently diagnosed as Type 2 in early November when I was sent to hospital with BS levels in the mid 20s Since then I have been on a low carb diet and taking two 40 mg Glyclazide tablets a day. My levels are now on average around 4.7-5 each day. Currently I am awaiting an appointment with my surgeries Diabetic Nurse but they have suggested they will put me on Metformin.

I am always reluctant to just change tablets and I have been ok on the Glyclazide so the question I would ask 'Is there any particular reason to change to Metformin'?

Thanks

Steve
