It is caused by a biofilm in your intestines. You have to do a concord grape juice fast for at least 30 days and also peptodismal. Peptodismal destroys biofilms very quickly.
You also need to take psyllium husk every day and a large amount like 1 table spoon. It will help soak up and remove the loosend biofilm so you don't reabsorb the toxins.
