I've written about this here before. It takes having the right acupuncturist. Just like anything, there are people who are talented and those who are not. If you find someone knowledgeable and good, you can get great results with acupuncture. I was in remission for about 9 months or so with it some years ago. I went 1 or 2 times a week at first; then less often as I felt better. It was truly amazing and helped stop my symptoms within a few weeks.
The expense and time commitment can be a big deterrent to trying it. But it can really be amazing.
