Doing coffee enemas and fasting then nothing comes out. Doing coffee enemas and eating veggies and meat, than tons of copper comes out. If all my other detox organs are working, adrenals, liver, digestion. I see it every day. It sounds gross, but look in my toilet and you will see that this certainly is cleansing, the dokter even calls it extreme. It is what it is. I am not lying. Coffee enemas are a sure way to see if a detox is working. This is my experience, maybe i have different form of pfs. Who knows.
