Have any of you all ever gotten a CT scan and had to drink the barium sulfate and be injected with the contrast? Does it mess up your stomach? I did this yesterday morning and I still can't keep anything in me. I've taken everything I can think of... Pepto Bismol, Immodium, Pepcid. I don't know what else to do. I've drank tons and tons of water trying to get it out of my system. Any suggestions? I'm starving!
