how to liver flush after master cleanse?

I am currently doing The Master Cleanse w/ p & b shakes as well as a parasite cleanse. i read you can finish The Master Cleanse with the liver flush. i want to try Hulda Clark 's method but i have a couple of questions
1. do you have to transition back onto food before you do the liver flush?
2. i started the parasite program at the same time as the master cleanse. i don't think i will have completed the entire program before my 10 day fast is over. Will that be okay to do the Liver Flush even though i haven't completed the parasite program?

any tips would be greatly appreciated! thanks. Tweet
