Funny, I've been asking the same question on the liver cleanse forum, and no one has answered me either!
I plan to begin The Master Cleanse in the next few days, as well as a parasite program, and I had planned on doing the liver cleanse immediately after. Like you, I'm just not sure if it's too harsh to go right into. Also, is it going to be tough to poo out stones if we have no poo left?? :)
