Hi,
I also never had bleeding, but I have parasites.
Maybe You should really get this checked.
I am doing NB since last March, last January I did a Master Cleanse and eliminated huge roundworms.
Later I have seen Tapeworm segments and liver flukes with the coffee enemas.
Actually a posting by Onwards encouraged me to really take care of those infections. That's what I do since two months.
My experience has been that You need much higher dosages for a much longer time than normally suggested.
Further down is another thread with a program. //www.curezone.org/forums/fm.asp?i=2036231#i
This program for example uses 8-12 capsules of Zymex II per day.
Normally You have to take 2-1-2.
I also use 1 oz. of Black-Walnut tincture per day. 10 days on, 10 days off etc.
