Magnesium sulfate / potassium sulfate / sodium sulfate
"Currently on my first dose of Suprep. I should mention, I'm 20 years old and otherwise very healthy, I drank the whole first bottle with water in about 10 minutes at 6 pm. The taste was honestly horrific, I almost puked it up every time I sipped on it (so I finally just chugged it).  I think I'm going to dilute the second dose with more water because it was so salty I wanted to vomit.



It's now 7:25 pm and I've gone at least 15 times. Everything is running clear already so I really don't want to do the second dose in the morning... But alas, it is what it is. I've been ridiculously nauseous since I first drank it, been trying to keep up with my water intake but have come close to vomiting several times so I'm trying to take it slow."
