I posted the whole thing, the excipients, etc. on the GERD forum, so I won't post again here. Just here to say that if they tell you there's nothing but barium sulfate and the bottle is labeled E-Z Paque, it has saccharin, sorbitol, carrageenan, strawberry flavor, other stuff, much of which contains sulfite.
I'm sitting here with migraine type headache, nausea, tinnitus, tightening of the throat, after asking about it. Resident said nobody has ever had a reaction, but there plenty, including death, listed on websites.
