It doesn't hurt to do the P&B while not on The Master Cleanse -- it's still good for you.
What to eat tomorrow: homemade vegetable soup. There's a good recipe idea in the book by Stanley Burroughs that's online. If you don't have a link for it, come back here and ask. Many of us have it.
Brown rice and barley are wonderful to eat after your day of orange juice, too. I have it in my veggie soup.
Miso, too, is good, if you like the stuff. I know very few people who do, but I love it!
