Should I do a Liver Flush while on a Juice Fast?

I did not do a Liver Flush before my Juice Fast but I was wondering when do I do a Liver Flush?

I've read I'm suppose to do it after the fast?

Today is Day 9 of my fast? What do you guys recommend?

Can I do a Liver Flush and a Juice Fast at the same time?

I'm 30 yrs old and never did a Liver Flush before and this is my first juice fast.

Thanks guys.
