ACK! Half a CUP of castor oil!!!??? Man! One to two tablespoons is generally recommended -- I do 1 T. the night before pro colonics with BIG results. I truly cannot imagine what half a cup of this stuff would do.
Early in my cleansing career juice fasting (or the MC) was tough. As I have gotten successively cleaner it has become easier and is actually pleasant, something I truly look forward to two or three times a year.
This cleansing diet looks delicious! Would require some planning, but so does anything worthwhile. It would make a nice break to a fast.
