Clysodrast enemas

Has anyone ever gotten an enema with Clysodrast in it? read about it on a Radiology site. used in Barium Enema preps.....

I had it many years ago as part of a BE prep. As I recall, first there was a bottle of citrate of magnesia then two tap water enemas the evening before. Next morning there was a 1 litre tap water enema containing the Clysodrast powder. So here I was expecting a nice comfortable enema (which it was) and then the cramps set in. Starting with the ascending colon they rolled through me like an old tooth paste tube squeezing out everything in it's path. Probably my worst enema ever from a discomfort perspective. Lasted about 10 minutes then things quieted down and I went to my BE. That, by the way was uncomfortable, but nothing like the cramps from the Clysodraft enema.
