How much Epsom salt for 4qts and if so, added to what other additive?

I have done Epsom salt with baking soda as a final rinse. Maybe 5tbl spoons to 4qt and 5tbl spoons of soda. Does Epsom salt have any other purge affects if added to any other additives? I have heard others use it with a soap but has bad residual affects afterwards. So what is you solution with Epsom salts?

I have done 3-qt Epsom Salt and Ivory Soap enema to begin a cleansing sequence since my teens.

What I do is, I start off with 3 teaspoons, then I add 1 teaspoon for every 20 pounds I weight. That is based on weighing myself on an empty stomach,

Any enemas after that are just soap suds, no more enemas.

Not everybody reacts the same to the strength of different solutions, so take my comment here with a pinch of salt (pun intended).

When I use epsom salts and/or bicarbs in an enema solution, I have found that about 2 tablespoons (heaped) of either in 3 quarts produce not only a good purgative effect but I have to make several return trips to the toilet over the next few hours after the initial expel. No good if I do an early morning enema before work. I can only imagine what 5 tablespoons of each in 4 quarts will do to me.
