I've had CFS for 3 years. I've spent probably one hundred thousand dollars on treatments. I'm on every hormone you can possibly replace. I've ran multiple treatment protocols. I recommend you guys try double the dose of doxycycline standardly prescribed. 200mg 2 times a day. The reason I got interested in this bacterial theory is because I had constant symptoms of bacterial infection. Burning/very foul smelling stool, acne, etc. I even had symptoms that Dr. Hyman (who is now dead) said were related to bacteria infection like joint inflammation and high blood pressure. I had gotten on high blood pressure meds and still it was out of control. Even scarier, just like I had read from the work of Dr. Hyman, I was passing this CFS to girlfriends. They would come down with stomach problems and chronic fatigue. They would even say "I feel like I can't lift my body". These were girls that had extremely healthy immune systems before meeting me. Just like in the article of Dr. Hyman and his colleagues where patients would come in and the whole office would come down with CFS. He would treat them with IV or higher dose oral antibiotics and their CFS would disappear. Google dr. hyman and all the results. His first name is on the link below which may help. Naturally we don't come across people who claim to have been cured of CFS. I stumbled upon links to this guy http://articles.cnn.com/1997-02-19/...ions-sick-veterans-chemical-exposure?_s=PM:US 200mg doxycycline twice a day is helping me unlike nothing else really. And I have had stool tests done from regular labs which show no out of place bacteria. All my problems started when I went to Mexico.
