Magnesium citrate
"Oh my goodness, this works like magic! For two weeks I had been in severe pain in the tummy area. I ended up going to the ER thinking there was something wrong with my gallbladder. Only problem was that I was SOOO backed up. They told me to drink some of this and it would work in an hour or so. Lets just say it was a river haha!! If you plan on taking this, make sure you're by a toilet! Once it starts you won't stop for a bit. Also remember to hydrate before and after. Before going I personally felt a little bloated and uncomfortable. But once it works you'll feel much better!"
