Would You Give Yourself An Enema to Stay Hydrated? Dobbs | January 12, 2010 | Survival | 3 Comments I would have to be near death before I tried something like this: I like how Bear Grylls says this should be only undertaken as a last resort, no s**t!

I currently call the Aloha State of Hawaii my home. 3 Comments Reanne January 17, 2010 I use enemas to hydrate all of the time. it is actually a good way to re hydrate instantly. macglboalus October 18, 2010 Actually enemas do the opposite they dehydrate you. Minerals are absorbed at the large intestine. Having an enema is the same as having liquid diarrhea. It takes hours days for the large intestine to absorb minerals. So if you are going to replenish minerals up your ass you must hold on to whatever mix you are using for no less than 8 hours and, as I remember, it is just about impossible to hold anything delivered as an enema for more than 15 mins. animal April 1, 2012 i use enema’s for sexual application. to be honest, with a bit of training, it is possible to hold enema’s for longer than 15 minutes. my record is 5 hours, but my boyfriend is able to hold it for almost a day. ofcourse, what comes out of it after that day isnt a too pretty sight. you cant really call it diarrhea, but neither solid feces. comparible with horse droppings.
