I was taking Metformin and Victoza. The Victoza made me sick. I was changd to Metformin and Januvia. My A1c is 13 for this period. I ate a few things I should not have, but not enough in my opinion to cause it to go up from normal last time checked (6. something). The greatest change in this period is that there was a yeast infection. Tell me about the Metformin/Victoza and Metformin/Januvia combination and the effect that the yeast infection could of had.
