morning!
if your packaging is the same as the ones i had, they come in a cool little acordian style bottle that doesnt allow things (poop) to get sucked back into to.
these things, and proctosedyl suppositories, saved the last 10 inches of my large intestine and my colon from getting removed, they were great for me, hope they go as well for you
try doing it yourself, not for dignity reasons, but for comfort reasons. you can feel what hurts and what direction to place it in side you.
also, see if they're a normal enema, or retention enema. i made that mistake to begin with. retention enema's are supoosed to be "swallowed" by the body. i.e. dont poop it out straight away. hold it in as long as possible.
i found hands and knees position the easiest for me.
good luck!
