It sounds like you are having a very productive cleanse! I was still passing solids at 30 days and so I knew it meant there was a need for further cleansing.
My past history included prescription meds and lots of time recovering from a car wreck which seemed to trash my metabolism between the pain killers and lack of exercise.
The good news was that the cleanse was doing what it was supposed to do and as it loosened the old fecal debris, the SWF (Salt-Water-Flush) flushed it out and my belly noticeably felt so much better and I have kept up the lemonade habit one day a week.
I plan on doing another longer fast to go to a deeper level. I am determined to flush until no solids come out. In between the fasts, my eating habits have improved greatly and my digestion has been great.
For me, the signs of success were good digestion AND good elimination. I did achieve that....
