If you've tried this--how long is considered long enough to eliminate the food? I'm finding info that's conflicting or not from credible sources.
And, once you eliminate the food for a period of time, how much are you supposed to deliberately eat to see if you have an adverse response to it?
Also interested in others' experiences with trying this. Did you discover you were/weren't sensitive to something you guessed you were? Was it hard to give up the culprit food? How did things change for you once you gave it up?
