That is correct. A case study of 1 -- not really that far off from the tons of mundane psychology studies that get published with Ns not much larger but with much weaker study designs and questionnable results. I'm not publishing my results in a journal (NEJM) because I don't need to convince anyone with high blood pressure to try this approach. My results are informational. The 478 breathing technique is Dr. Weil's, not mine. As I said, it works for me and I have the data to back up my claim. What have you come up with that might be of use to the health community?
