When I take epsom salts it is like a flood that follows. It starts about an hour after I take it at 6:00PM on Saturday and doesn't stop till the following day. Boy, by the time I am done with the flush, I am so cleaned out that nothing could stay in there. It also removes alot of your minerals and so I eat as much watermelon as I can the second day. Very easy to do. Just don't go very far away from the bathroom and don't think you have gas, you don't, lol.
Plus the main purpose of the epsom salts is relaxing the liver's hepatic ducts. That is it's main purpose and is very important in getting the crud and stones out of your ducts. You can take it in other forms but I don't know allot about it, I just use the epsom salts.
