I had an IV saline drip once when I'd gotten badly imbalanced during detox. From ER stayed overnight in hospital w/ IV. The MD wanted to keep me longer, but I declined. I returned home and gave myself saline by enema. The IV left a nasty bruise/discoloration, which I felt was quite likely due to some additive rather than injury at the site. Having learned what I did wrong to become sodium-depleted, I'm unlikely to find myself in this situation again. I would always opt for enema or footbath rather than IV.
