Hi @DKFusion
We brought your question to Dr. Joseph Murray, a gastroenterologist and celiac disease expert at Mayo Clinic. He responded with this video reply.

I can definitely understand your reluctance to do the challenge again. How long did you try the challenge and how much bread did you eat? Will you try again?
