How long can you do epsom salt flush?

I am actually doing The Master Cleanse and been using Epsom Salt to flush out my system because I have no Sea Salt . After reading the information in some of these forum, I have found out that it is good for the liver flush. Am I correct here? I have Hep C and am wanting to flush my liver anyways. The package says not to use as a laxative for more than a week. I am planning on doing the Master-Cleanse for 15 days. Please let me know what is up with this. Tweet
