How do we know it´s a reggression and not an infringement?

[Guest guest]

I´ve been reading about regressions while doing this diet. How can we be

sure it´s a reggression and not something he ate?

How long will these regressions last?

I post a questions, days ago about the use of a gfcf dishliquid, but I´m

wondering how can we be sure that at Restaurants or when we go to visit

somebody , they will be washing with a safe dishliquid. Should we carry our

own forks, dishes, soaps and so on? How strictly this diet has to be?

Thanks to all.

Carmen.
