I have don 24 flushes during the last year, and I totally agree with slider25.
I donīt feel god after each flush, in fact, after some flushes I have felt miserable. But in the long run my health has improved a lot, and iīm happy that I didnīt give up. The health improves in small steps. Big fluctuations are most likely temporary. At least thatīs my experience.
