Hi there, thanks for the valuable lead. I however still highly suspect a parasite (Blasto Hominis) that's causing all of the symptoms. Eventhough you did a parasite cleanse, Blasto Hominis is NOT an easy parasite to eradicate. It usually takes "a few months" until it is fully flushed out of your system. I am however still open to the possibility that it might be caused by msg. I read the info in http://www.msgmyth.com (as recommended by Jolts). I guess I will try having a non-msg diet for 3 days as well. Thanks again for your suggestion. Keep in touch with our progress.
