Magnesium sulfate / potassium sulfate / sodium sulfate
bowel preparation
"In the middle of my first dose. After reading other reviews I was positively dreading it. Now it wasn't exactly tasty but I just gulped it down and occasionally bit down a lemon wedge which really helped. It wasn't until the last few swallows that I had to give it a bit more effort because the taste was getting to me. My Dr's office told me I could drink GatorAde instead of plain water after finishing the prep bottle #1. I did not have anything cold because I prefer room temp. It took 35 minutes to start working. It's been 2 hrs and I've gone four times with no cramping, chills, nausea, etc.  Things are already starting to be more clear.  I'm really glad for the low fiber diet and for pushing fluids all day today. Not staying long on the pot either"
