hello,
from your letter , it is not clear how long you were on this drugs, what is your present glycemic status, your age ...
I would suggest the following plan of action
1. get your Diabetic tests done, complete with
HbA1C, BUN,eGFR and lipids
2. according to your results, there might be a need for reviewing your treatment regimen, you may consider starting analogue
insulin once a day along with DPP-IV inhibitors and
Metformin for some days then repeat your tests and titrate
3. check for complications and do
consult a Nephrologist, cardiologist and ophthalmologist soon
4. ask your doctor to advice on self monitoring of blood
glucose and specific timings
5. pl look into lifestyle modifications with a proper planned diet and exercise regimen
hope you get well soon
