this time around. Detox is detox and it passes, if you feel even better afterward, then I am always sure that is what it was. I judge how rough a cleanse is by proportion of detox days to feeling good days... four to nine is rough. However, if you hold on and ride this wave out, the next 21 days might sail by easy peasy. Each cleanse has it's own identity. No two have been the same for me. End on an up day.
