Phosphate enema

Been chatting briefly to a woman who says she adds phosphate to water for her enemas, any idea what exactly it is or where you get it ?

Im well aware of the small disposable phosphate enemas, so to save time, i dont need any info on those.

Sodium phosphate and sodium bi-phosphate is the active ingredient list in Fleet enemas and their generic.

I suspect that she is simply unscrewing to top of one or more Fleet(or generic equivalent) small volume enemas, and adding them to a bag with soapsuds or glycerine or similar mix.

I think you can pretty much find Fleet or it's generic equivalent anywhere.

Drug store, grocery store, big box, Independent Pharmacy, wherever you are going anyway.
