If you read the book from Andreas Moritz the Key to Health and revuvenation, and his other book The amazing liver cleanse, I think it will help you understand your symptoms. I am posting a link to his forum. You might want to do some research on virgin coconut oil for hypothyroidism, and it apparently helps with IBS and the such.
