Magnesium citrate
"Well,  was backed up for almost 4 weeks. After 2 weeks went in to ER, got lactulose. No success after being told to eat more fibre too. Went back 4 days later.  I had an x ray that showed a lot of stool. Try some citro-dan. Had little success. Took another the next day. No success. Was getting pretty rough. Went back and told to try restoralax. 3 days and was able to go  a little bit but it would not budge the rest. Went back again. Told to try suppositories. Well been using them every night for 4 nights. Decided to use one tonight also took latulose and fiber tabs and metimusul. Had some BM. Took Citro-Mag after BM and water. 2 hours later I felt al ot come out. Was getting a pale clay look of stool before. Got back to normal color and running. Hope it stays clear."
