Cant say I have Jim. I do need to be carefull what I put in. MANY things have gluten to which I am highly sensitive.One good shot of that,and I'm suffering for at least a week. Barley I believe,is related to wheat and not gluten free.Many prescription pain killers have some sort of gluten related ingredient. Hell,it's even in rice krispies hidden in the name "malt". Not sure why the food industry,among others has chosen to hide what is really inside what we eat.
