constipation
"After my doctor found "bad" polyps during a routine colonoscopy one year ago, I have to go thru the procedure again (tomorrow).  I took the magnesium citrate at 11:00 am and exactly three hours later, it started working.  After reading all of the previous reviews, it seems that it works for everyone differently - some rather quickly and others like myself several hours later. Drink lots of water with it to stay hydrated and walk around your house to get your system moving."
