Magnesium sulfate / potassium sulfate / sodium sulfate
"The taste is sweet and salty, like cough medicine. I highly suggest using juice or Gatorade as a chaser after drinking the prep. I felt nauseous and like throwing up, but drank water after Gatorade. 10 mins Later I felt the effects. Do not leave your house, use babywipes or water to cleanse after every bowel motion, stay near a bathroom, use Depends if you are concerned you can't make it to the bathroom, and eat chicken broth to soothe stomach. Stay away from acidic juices because your bottom will hate you for the next 4-8 hours."
