I was never Dx with sleep apnea but did snore. I have been gluten free since July 2010. Now that you mention it when I viited my daughter in Canada 3 mos. into my gluten free life she did mention that I no longer snored. I attributed it to the 25 or so lbs I had lost at that point (I've now lost more than 70!) but maybe it was the gluten free diet itself. Interesting!
