The good news is...

...you can skip the tea and just do a SWF (Salt-Water-Flush) to give your self a break.(Not Master Cleanse protocol though) I know other posters have stopped doing the tea after a while because of what you are describing. Just make sure to do the SWF (Salt-Water-Flush) every morning. Even if your bowels are empty you are still dumping toxins in to your system that need to be eliminated. Maybe go to tea every other night or even every few nights. The tea was really the only thing that made my last Master-Cleanse hard as it disrupted my sleep and made me feel....crappy. Sorry couldn't resist:-)
