You bet--we'll keep you posted. We haven't noticed any stomach issues to this point . . . . From the way the stools look, I can't help but think there is greater absorption. Weight is stable (but we never had a weight problem, so we are fine with that). We did notice one interesting thing. Our littlest one with CF (age 7) used to get ravenously hungry at night and eat several bowls of cereal before bed. After being on the arginine, he still eats some before bed, but definitely not as much--and his weight is still stable! That suggests improved absorption to me. We haven't noticed any changes in eating in the older two kids with CF.

I am glad you've added the oral GSH back in Carrie--I think that is a very good move!
