I do coffee enemas, with a bucket and a long tube, from sawilsons.com. I lie on my left side to put the 101 - 103 degree F. coffee in, up to a count of 6 each time I open the valve (with the tube a foot or so up in there). It takes 15 minutes or so for all the coffee to go in (then I lie on my left side for another 20 minutes).
