Any theories on why gluten may impact those in withdrawal?

Hi All - I have never had an issue with gluten before my withdrawal from Ambien ( zolpidem).  During acute WD I started eating clean, and avoided many foods including gluten.  I've added many things back but remain on a clean whole food diet.  Most every time I attempt to introduce gluten back I feel "off".  There have been times when I eat a piece of pizza and feel fine the next day, but most other times I experience an uptick in physical symptoms. 

My only theory is that WD impacts our gut health and gluten exacerbates our symptoms.  I'm hoping this will abate once I'm fully healed, but looking for others to chime in with their experience and thoughts on the subject.

I wish you all true and swift healing.
