Magnesium citrate
"Well, I promise if you are reading these reviews they are all true! I have been on the toilet for the last hour, stuff just streaming out of me. I have been incredibly constipated for the last few weeks and I remember my mom always used mag citrate whenever she was really backed up, and oh lord do I know why, I don't think there is a single bit of poop left in me but it just keeps coming out. The only downside is that my bottom kind of feeling a bit hot, and that my stomach won't stop making these god awful noises, my boyfriend was like oh my god what's wrong with you hahaha. But as everyone else has said be prepared to be on the toilet for a while."
