K.R.
I'm trying it now, for migraines that are slowly getting worse. I think it will work, but am switching to a new acupuncturist, because the one I first went to (for the convenient location) isn't the right fit for me. She is wayyyy too into herbalism and a bunch of non-scientific mumbo-jumbo. (So far, after four visits, things were a lot better at first, and then I had a stressful week last week and got three migraines. So I can't really tell yet if it's working or not.)
Next week I will switch to someone who comes highly recommended. I can't recommend her to you yet -- because I haven't seen her yet.
I am very interested to see what other people say.
