Magnesium citrate
"I took Magesum Citrate (about 7 oz) before I went to bed and woke up ready to release. This is very effective, though it can take a while, and personally, it was pretty hard to down the bottle. The taste isn't bad, I actually kind of liked it, but it was very sweet and stayed in my mouth, not anything too dis comforting however. Overall, this works like a charm, but it can be hard to swallow and works slower than other medica tions for constipation."
