Lack of LBB is why you are probably having problems cleansing. The LBB keeps the trash moving out of your system which is crucial unless you want dead parasites rotting in your digestive tract. When parasites die their bacteria start to eat them alive and you get sick and you feel it. Been there and its not fun so take the LBB. Barefoot's herbs are great and you get more bang for you buck with his stuff than Shultz's in my opinion. Regardless some type of herbal bowel formula should be taken and is part of Dr. Sutter's suggestions as well.
#1 Clean the Colon
#2 Clean the Liver i.e. deworm and liver flush
