I had the same problem! I did a fast and cleanse and came back to NOTHING – I was drinking 4 litres a day and eating the healthies diet I ever had. I have suffered from constipation for many years so I was frustrated but my acupuncturist put me on some herbs (peach stone, apricot stone and linseed) and I have been going every day. I started on 8 tablets a day and I’m down to 5 now but the best thing is that combined with the diet, it’s teaching my body to go AT THE SAME TIME EVERY DAY – this is the most amazing thing to me!
So, you may just need to kick start your body into getting used to the diet. As my acupuncturist said, it’s in a state of shock and confusion!
