I'm working through a probable glutening as I type. Although I have been fortunate not to have gotten glutened too often in the past 8 months I've been gluten-free, I have noticed that it takes anywhere from 6-12 hours for me to register any sort of symptom.
As far as I can tell, my metabolism is a bit sluggish -- always has been. I know some of you can tell very quickly when you've been glutened; does anyone else get an unpleasant surprise much, much later???
Thanks, and eat clean!
