This is the one I use. My hubby did it with me last time. When I'm coming off the MC, I just do one day of fresh apple juice (green apples) and then the next day I do the apple juice until 2 pm and then flush that night. I make extra apple juice the morning of the flush and mix it with the Epsom Salts instead of water. TIP: Use a straw to drink the Epsom Salt mixture if you can't take the taste. Put the straw as far back as you can without gagging yourself, and just get it down.
The other important thing is don't have anything that needs to be done the next day. You'll need to be close to the toilet for the morning, and perhaps the early afternoon. I use a colander to "catch" my stones (bought at garage sale).
P.S. I don't buy anything to help me sleep. That's not a problem for me. But I do move it all 2 hours later so that I'm going to bed closer to my normal time.
