I also did the candida diet at first, didn't help, and did gluten free. I have an appointment with a nutritionist to help me with the fodmap. It's hard and like you said sugar and high fructose corn syrup is in everything!!!! I also have a breath test for fructose coming up. I really feel it's all from the sibo. Did you ever do the Xifaxam with the alternative meds together? I think my son has SIBO as well. I am going with him on Friday to a naturopathic. She was at the sibo summit with dr. Allison. The first visit is 1 1/2 hours. That is encouraging.
