If it gets too stressful, then pick a diet you think you can honor for 1 month, and you could move forward from there.
I think if you are one of the people who are having difficulties on such a strict diet, then perhaps they can benefit from a “pit stop” diet, where they add very low sugar items like blueberries or almond butter, more chicken, etc. to their daily salads and anti-candida veggies. I’ve done this and its kept me from eating big cheat items like pizza or cookies.
And beyond the diet slip ups, you have a lot of stress coming from all angles. I have benefited from seeing a psychologist during my journey with Candida. It has helped my perception across the board. I highly recommend it for candida sufferers, especially if you have insurance that covers it.
