The nystatin won't do much good if the diet hasn't been adjusted. Also you can get enough die off from the diet alone. I'd be careful about mixing the two after you have cheated. You may want to save the nystatin until you are well and truly back on the diet and have been for sometime.

Nobody enjoys this diet, particuarly around Christmas and I totally understand what you are going through. But you have 2 choices. Either you continue to be loose on the diet to enjoy the foods around Xmas and suffer the consequences and possibly need more antibiotics for UTI's, (The antibiotics will in turn cause a worse condition of yeast long term).

OR, you can consider the downside and pick yourself up, brush yourself down and get firm on yourself for the sake of your health and quality of life. Without improved health, there isn't much joy anyway! Food is enjoyable and is one of the pleasures in life, but frankly it lasts a moment compared to the long term consequences.

I would concentrate on healthy foods and exclude all the enemies - all things containing sugars and the high carbohydrate foods. Depending too on your candida severity. Some can handle a few more natural healthy high carbs than others. I cannot.

You may wish to also take a probiotic to help you after your antibiotics. You should do this for weeks or even a few months to replace the good bacteria. I have to do this too. I'm buying one soon because I don't believe I ever replenished the good bacteria after my course of antibiotics and evidentally a week aint long enough.

I wish there was an easy and quick way through this, but there isn't. It's about getting back on track, staying there and gritting your teeth and bearing it! There is no fast track to getting there. No easy answers. Sheer determination and discipline/will power.
