I am diabetic suffering from diabetes since last more than 10 years I am aged 66 years. Since last few months my post lunch counts are more than 300 & now it spiked to 400 post lunch. Should I start taking insulin injection at home, if so, how much In the past I used to take Daonil & now Glycomet 500,(3 times a day). Can u suggest to better option to control my sugar level near to normal?
