Want to do Liver Flush. Is it necessary to consume 4tbs. of Epsom salt?

I really want to do Liver Flush even though my adrenals are weak. My question is why is it necessary to consume 4 tablespoons of epsom salt? can we cut it down to say 3 or 2 tbs? Right now I'm doing parasite cleaning and want to start colon cleaning protocol. what are some ways to clean colon? I'm unemployed so can't spend alot money. Anyone know any home remedies that i can try?

Also once in while I'm having some minor abdominal pain. it stays for few seconds then gone. Could it be because of fatty/toxic liver? I'm tired of being tired. I assume since liver consider an engine of our body, my ardenal and thyroid condition will improve, once toxic will start flushing out of body? Any advice will be greatly appreciated.
