What went wrong

I tried to do my second flush last night. I did one 3 weeks ago and passed over 100 stones, but this one gave me nothing but clear diarhea. I followed the clarke formula, the only difference was I did everything 1 and half hours later ie 2pm = 3.30 pm etc. I did have a few pieces of beetroot around 8pm to keep the hunger pains at bay......but I did this before without a problem?

My G/bladder now has a dull ache......any ideas what prevented a good flush?
