Gluten free diet helped, but...

Gluten free diet helped, but... I've given gluten free diet a shot, after kicking gluten out entirely out of my diet I've had almost zero stuttering and almost no anxiety whatsoever. But the thing is, this only lasted for 3 days until it went back to normal even though I consumed no gluten. I'm hesitant to chalk it up to placebo and I'm wondering if anyone has had any similar experiences with changing their diet in order to help their stuttering issue.
