lorig & Rose,
I did Zhang's for 6 months, and felt I made progress on it, but I felt I had stopped improving so I switched to Buhner's. Dr. Zhang's is expensive over $300/month. Buhner's at full dose is about 1/2 that. I had a problem with the Andrographis (I had a severe lessening of taste, not a complete loss), but I emailed Stephen Buhner and he suggested subing Siberian Ginseng for the Andrographis. So far so good.
lorig, you can do a search for Dr. Zhang lyme disease he offers a free phone consult, he request that you read his book first and fill out a questionaire.
Rose, I use the 1 person portable sauna that you sit in with your head outside, it kind of looks like a toaster. I love mine.
