Here's a post from just a few days ago asking the same thing - hope it helps! I think that a liver flush is a super way to wrap up a master cleanse, if you can schedule it. I think you can just go from drinking the lemonade right into your flush. Hopinso suggests a day or 2 or apple juice drinking, to soften stones (the malic acid softens them) and then do the flush. If you would combine that advice, you would finish your cleanse, and then maybe do a full day and a half of lemonade (to keep the hunger at bay) and apple juice, and then start with the epsom salts drinks at 6 pm and 8 pm, and then do the flush at 10. In other words, if the last day of your cleanse was Friday, then all day Sat. you would drink apple juice and lemonade, and then again on Sunday, till 2 PM, when you have to stop drinking. Then Sunday night you would start with the epsom salt drinks. I hope that makes sense.
