I have CFS and my mom  has FM. We both have Epstein-Barr virus. I talked to her about treating it with enzymes using the Dr. William Wong method: http://www.life-enthusiast.com/index/Articles/Wong/Viruses:_Fighting_and_Winning You step up the dose by +1 capsule each week until you feel the results. She is up to 6 caps/day and it hit her real good. Not a herx reaction but less depression and less pain in movement. She usually has to use the electric cart at Walmart, well, Monday she pushed the cart! As of Wednesday, she is still moving around better. I asked her which brand of enzymes she is using and she got a big bottle of them at Walmart for ~$7. She had just used up some other [special for FM] brand.
