anyone here gone for an abdominal ct scan? my dr is sending me for one and I didn't realize you have to drink 32 ounces of a contrast solution, I'm not sure which, I'm reading there are two kinds, a chalky and a clear, but I'm sure I read somewhere on this board that the chalky one has made some people more constipated than when they were before and I'm terrified of that, if there is a side effect or a bad reaction that can happen it usually happens to me--any feedback/experience anyone has with this would be greatly appreciated...
