I've read bits and pieces, but I need to sit down and read through it from start to finish. And absolutely! I've done various cleanses/detoxes in the past two years and it is surprising and disgusting what the results are. The craziest was the parasite cleanse. After the first round, I was having god-awful migraines and terrible nausea, but I didn't pass anything. After the second round, my body was disposing of them left and right! (TMI, sorry!)
Detoxing is never a bad thing! Even for those that feel completely healthy.
