Every time I did a parasite cleanse, I felt better for awhile and then the stomach problems would come back.
Do you have candida?
At one point, I just forgot about the candida and worms and just starting putting back all the vitamins and minerals my body was lacking. Worked well for me, but I have no idea what your problems really are.
For me, it was my liver and gallbladder caused by toxins etc...
