Magnesium sulfate / potassium sulfate / sodium sulfate
"Sure, it's not a pleasant experience, but when you see a "horrible taste" review, move on to the next, they're reality tv princesses with their best drama story and NO advice. Drink it standing. In 10 minutes it started for me and lasted 2 hours. Just try to relax on the toilet with a book or movie to help pass the time. Dab don't wipe. Fortunately I have very regular movements. If you don't, I suggest prep for the prep a few days ahead. Avoid "clogging" foods and take a laxative if you need - you don't want the bloat, cramps, headaches, etc. that others complain about. I over stressed because I got sucked in to those horror reviews. I realize it's different for every body, but it's not THAT bad. I thank those who posted genuine tips"
