Magnesium sulfate / potassium sulfate / sodium sulfate
"I knew pretty well that the drinking part would be hell. When I smelled it (why do people always do that?) basically the only thing that came to mind was cherry cough syrup, which I usually puke up anytime I try to take. I know it said to mix with only water, but if everyone on here is licking lemons and drinking chasers. I mixed the 6oz solution with about 4 oz of lime juice and 6 oz water. it wasn't unbearable. Drink it on ice and with a straw btw. 

For me, it took 3 hours for the first dose to work and about 5 minutes for the second bottle the next morning. Towards the end of the 1st cleanse, my poo looked like urine and I thought the 2nd wouldn't do anything but somehow it found more to expel o_O"
