i have learn the best way for me is lying down on my left side with enema bag about two feet above level of injection, using warm and soapy water. allow water to flow slow, if it gets to feel like you can not hold it anymore. stop the flow for a moment and continue when the urge to defeciate ends. do this as many times as possible until you have to defeciate. this has always worked for me. hope this helps. i do use a two quart,openn top enema bag and also the rectal tube, not the douche nozzle.
