Yeah, acupuncture these days is kind of tough, I guess. I'm tight with my lady, so she's gotten me in a couple of times the last few months, but I feel weird about it.
I'd just tell them you were anxious, what you're anxious about, generally. I talk to my practitioner as if she's my therapist on that level; obviously not in as much detail or as deep, but for how I want her to tailor the points, I just give her all the info, in addition to whatever physical issues there may be.
But even if you don't buy into the methodology, and I'm skeptical, it helps me to have those points in there, think about where they are, how they connect to each other, how my body connects to itself...and breathing deeply and just kind of using it as a meditation opportunity as well, it kind of focuses where the issue might be. But I don't know about meridians and stuff like that. It has just chilled me out and relaxed me very well for a few years, so I stick with it.
