hey, Sea Salt water is great to cleanse the entire intestine and it is safe. Yes you do get diarrhea. I have tried it so many times and it works. For some people it might not work because they must have not added enough salt or drank enough of the mix. You drink it first think in the morning and within 2hrs you would have to eliminate(several eliminations). I also lost a lot of weight by just doing it for seven days straight, also when you do it for that long it brings your stomach to a newborn stage and you have to be careful what you eat after.
