If you are into colonics it is no wonder why you deny the use of fiber to prevent constipation.
No one said that eating like a horse was the way to move stool but keeping the hard rocks of stool
from forming is a big help. Bread and pasta are big culprits in constipation and a slow perisistalysis
is another because the longer stool remains in the colon tha more dehydrated and HARDER it becomes.
IBS is mainly a self inflicted condition unless there is an underlying neurological problem in the gut.
