Magnesium citrate
"I have been constipated for 6 days. It seemed there was no relief in site for me. I took stool softener/laxative for a few days without any results. I then bought Exlax and took 4 pieces at one time. No result. I went to the ER as my stomach was hurting all up the sides and middle. The Dr. recommended Magnesium Citrate and told me to drink the entire bottle. I went to Family Dollar and it only was $1.25. I ate a sandwich prior to drinking.I drank the grape flavored Magnesium Citrate at 8:00 PM with 16 ounces of water. After a few hours, I was still in a lot of pain didn't feel anything happening. I couldn't even pass gas. at 1:30 AM It started. It is now almost 3:00 and I am still going. not sure how long this will last but I feel great!!"
