Magnesium sulfate / potassium sulfate / sodium sulfate
bowel preparation
"I am in the midst of taking it now. The instructions clearly say to drink 32 more ounces of liquid . After I nearly vomited finishing the actual prep. Then I had to drink the water. Give it a few minutes and I vomited the whole thing up. So I haven’t used the bathroom once since taking it at 7 pm and it’s now 9 pm. Hoping the second bottle does something, but might need to reschedule my appointment."
