What influences your blood sugar most is the number of carbs you are currently consuming. It is very hard to maintain a vegan diet without consuming a level of carbs that will elevate most diabetics blood glucose level to an unacceptable range.

My own tolerance is between 15 & 20 net carbs in a 3 hour period. My A1C was 7.2 at diagnosis, but I got my blood glucose levels within normal range in 3 days exclusively by changing my diet. I can count on 1 hand the number of times my blood glucose has been outside the prediabetes range since October, and on both hands the number of times it has been outside of the normal range (aside from persistent dawn phenomenon that puts my waking blood glucose in the 100-110 range about a third of the time. Based on the averages of my testing (~4x/day, looking for highs), I expect my A1C to be in the low 5 range.

If you want to consider a low carb diet, you would need to work carefully with your doctor because of the januvia - which dumps a steady stream of insulin into your bloodstream. Insulin that doesn't have carb-created blood glucose to work with can lead to dangerous hypoglycemic spells.
