I have had CFS for 24 years. I am trying lots of different therapies right now. I have several friends who have tried IV ozone therapy for HIV and Hep-C, and both have gotten their viral loads down to undetectible within several months of commencing ozone therapy. The dosage is 360-450 mcg. per liter of ozone. I am doing it 2 days a weeks. I'm on treatment #6. If anyone has anything to share about this, that would be great!
