I drink about 6x8 oz cups of water a day - sometimes up to 10. I drank about 4 the night before, went pee a lot. I drank 2 x 8 ox of the salty water. Then did not drink anything more or eat for hours. One usual BM 2 hours after drinking the salty water. 6 hours later, I was very hungry so ate reasonable amount. No "flush" by 8 hours. 10 hour point had very positive (large amount) regular type BM.
Today I am 3 pounds lighter than yesterday. And that is weighing myself after all day liquid and food intake.
I was just expecting near "runs" - I will do this again, as drinking the salty water was not "that" bad. . .
