Hi sir.
Greetings.
Intially you are on sulfonylureas and metformin, then you have been shifted to sitagliptin and metformin.. It's not a bad move, but some times glucose control may not be as good as with sulfonylureas. So you may need additional drugs or change in lifestyle according to your glucose profile. It's difficult to suggest without your glucose values and clinical details.
