I am diabetic for last 10 yrs. Action.

you are on almost maximum dose of these medications. if the fasting remains high despite the combination , it is clear that you have become insulin deficient as well. For the medications to work , you need to have appropriate insulin release from your pancreas. But in individuals with diabetes, pancreas slowly lose their ability to secrete insulin and as such medications by themselves fail to get your sugar under control. this does means that you would need to have insulin to get the sugars under control. There is also a possibility that some of the medications can be stopped as they do not seem to have any effect on your treatment . Discuss with the doctor to have appropriate changes made to your treatment regimen.
