I started chiming in, but let me share my story real quick:
about 1.5 years ago I started waking up and having nausea on and off during the day, every day. It got worse to the point of being nauseated all day long and having heartburn and pain behind my ribs. After an endoscopy I was sent home with a prescription for "the purple pill". It didn't work, made it worse. When I went for a second opinion I was told it was in my head. At that point I decided to go alternative. A homeopath helped me along a little, but the nausea and discomfort (incl. heavy feeling in my stomach) never went away completely. I went to an accupuncturist who finally got me on the right track by asking me if I had any fecal tests done to check for parasites. So, last December I finally found out the culprit of my misery: blastocystis hominis, probably since the time I was in Asia (9 years ago). So, now I am trying to heal my damaged intestines, including my liver. I started with the parasite/kidney/liver cleanse and will continue to repeat the liver cleanse procedure. I am on a strict diet, which helps tremendously too. I am hoping to feel better and be able to eat without misery by the end of the year.
I look forward to similar stories on this forum.
