Hello Im Type2 Diabete.I Had Found Before 2 Months From

Hello
im type2 diabete.I had found before 2 months from now.Doctor started to give me glucophage 850mg but after 2 weeks time we change to galvusmet 50mg/850mg to decrease my blood glucose.The question is can i take back the gulco?Secondly i have lost almost 8kg for a short period of time.What shall i do to get back that weight?Finally,at morning fasting my BG is 6mmol and after eating going to 7mmol/8mmol with medication.Is there any risks for my kidney since Im having two tablets per day as Im also having blood pressure medicine (coveram 5mg/5mg) everyday at morning time.Many thanks.Yacoub.
