Magnesium citrate
"I wasn't able to use the bathroom for 3 days. Today I went to the dollar store to buy me some cherry magnesium citrate saline laxative. I drink 6oz of it and 42oz of water and hour later I was able to use the bathroom. 2 hours after that I had diarrhea. Thank God I was able to use the bathroom! No, more constipation."
