NIH was doing a study with Sjogrens patients for acupuncture and dry mouth. I was a participant in another of their studies for graft vs. host disease last year and they asked me to try it as my symptoms are similar to those of a Sjogrens patient. I was a skeptic but figured it wouldn't hurt to try, and I like being able to contribute to scientific research. I was pleasantly surprised that a single treatment brought a significant improvement. I asked my transplant doc if it might just be coincidental timing since I was nearly a year out from transplant but they thought not because the improvement was abrupt rather than gradual.
