Magnesium sulfate / potassium sulfate / sodium sulfate
"Listen!! if your reading these, stop doing this to yourself. Im 49-M and literally drove my self crazy researching and reading .. here it is in a nutshell. Place the 2 bottles of suprep in fridge night before. Eat a LOW FIBER DIET 2 days before and of course your liquid diet the day before. Mix in your chilled water ( I used SMART WATER) with the 6 oz Suprep. Use a big straw. not a thin one. drink as much as you can, use lemon slice, do again, use lemon slice, and i was done with it after 3rd time. drank two more 16 oz waters over next hour ( I used smart water again). this stuff just liquefies everything. 15 to 30 minutes later you will have liquid BM's.. No pain, no bloating .. just the full feeling of drinking so much .."
