Hi, Yes I have tried acupuncture specifically for headaches.  I was told it took 12 sessions to see results (it  may be different with others).  For me it didn't work... but I had a sense that all this acupuncturist wanted was $ so shemight have been making it so it TOOK 12 sessions.  It may work for some people, and in less time, but for me in the end all of it wore off, so it is a thing you'd ned to keep going to in order to keep the headaches away if it does work.  Good luck.  It would be n ice if you found some people who go to the same one so they can give you their feedback.
