My wife is doing the challenge along with me and we have all been having our cravings. I was commenting to her that within this first week she has been sneezing and coughing MUCH less than she usually does. She almost always does both when she goes to bed and when she wakes up in the morning, but I would say it has decreased by no less than 80% since following the PB nutrition for just the first week.
This morning she broke down and had some waffles with butter and syrup and her reaction was significant and almost immediate. Within 5-10 minutes of eating the processed grain and sugar she had what appeared to be a full blown allergic reaction similar to what someone might experience with "hay fever." She was coughing, sneezing, had a runny nose, felt tired... it was quite shocking. She got back on the PB plan for the rest of the day and the symptoms were gone.
Just an interesting incident I thought I would share.
Hope everyone is doing well with the challenge!
