I have had a constant yeast infection since the first week of January. I have tried several over the counter creams, 7 Diflucan pills, yogurt, peroxide, and take 3 pro biotic pills per day. I currently am having sugars in the high teens. My doctor keeps telling me it is from the sugar. I am o.k with that but I need to do something for the side effects until I get my sugar under control. I am on 2000mg Metformin and 21 units of Lantus at bed and 10 units of Lantus in the morning. Has anyone had this same problem? Does anyone have any suggestions of what I can try? This is getting to the point that I can not even sleep at night anymore.
