Well, i'm trying to think hard....This is one of the things i guess i won't ever get because i am in nursing school, i have worked on a surgical unit where like any other unit worked with ivs and fluid runts. So pumping something into my body that my body doesn't need just makes my mind go, what?

But i do understand that there are somethings out there that i wont get but are a shit load of fun. my suggestion is go to a medical friend and ask them causally about it. There are a few people on this site (i hope they're still here) that know alot about medical facts that are good to know. But my biggest warning is don't ever do something just because it was on a website. i go for in person classes/facts/face to face learning.

Off hand i cant think of any harm it is to inject NSS into. . .the BIGGEST caution would be to watch for fuild over load. that can cause serious problems. As to how much fluid to equal fluid over load i don't know off hand and i do believe it has a lot to do with the body.

There are prob a who bunch of things to consider when doing this sort of play, why i suggest first going to a medical person, or someone who has a solid back ground in the medical field (and you trust them).

Good luck.
