I had bleeding during a Liver Flush also, it was about a year or so ago. I had been doing P&B shakes a lot and I have no proof that they in anyway were invloved, but that was something somewhat different I had been doing up to that flush that I hadn't on the prior flushes. It was really freaky to say the least and quite conerning to me. I also had blood in my stool for the first few trips but it went away and you could tell by the looks of it (gross I know) that it was not fresh at that time but you could tell it was fresh during my liver flush. How often have you been flushing? Maybe it could be that you are over doing it and not giving your body enough time to recover? Just a couple of thoughts....I never really found out what caused mine but like I said, I suspected the P&B shakes and intaking enough water.....could be a total load but it is my guess.
