Shelley, I'm SO glad to hear you find the enema set up just fine, as opposed to the colema board, which seems like so much trouble to me (moot point, since I wouldn't even be able to fit it into my bathroom.
I have had people swear by colema boards.
But like you indicated, the humble enema set up is very flexible.
But why the bucket instead of a bag, when you can put in the same amount of liquid into a bag?
Also: with a bucket, don't you need to stand it on a surface? I have absolutely no such place/space in my bathroom -- inless I suspend it from the shower rod, which would be too high (don't you think?). If not, I can try this method.
