And when I did my second Liver-Flush (apart from the MC) I had the worst headache I've had in a long time. My first Liver-Flush was on the day after my 10-day Master-Cleanse and it went quite smoothly - lots of stones passed too, unlike the second one. So although I understand Somer's naturapath's advice, I have to say that for me it works better on the heels of an MC. God bless and cleanse on!!
