Hate the things, but at least they don't have the same effect as the prep stuff (for me anyway). I have administered them to myself which I prefer over the nurse. I just lay on the bathroom floor, right next to the toilet, squeeze in as much as I can tolerate and wait as long as I possibly can. It generates a "typical" bowel movement (as if us Crohnies have a "typical" bm!). The effects are not long-lasting. They typically have the patient repeat the process using a second enema.
For me they are very, very uncomfortable. Not sure I'd say painful, but hurts, yes. With all those ulcers and inflammation in the rectal region (for me), it's no wonder it's so bad.
