Question for the Experienced

I'm on day 15 and will be breaking my fast after day 21. I would like to continue to clean my digestive tract to remove as much mucoid plaque as possible and I would also like to do a liver cleanse. Can someone please instruct me how to proceed? I don't want to do the P&B shakes because I suffer from chronic constipation.

Do I wait several days or longer before introducing the olive oil into my system and what other type of cleanse is available to remove the mucoid plaque?

Any help will be greatly appreciated.
