Has anyone here tried neurofeedback for anxiety?

My T is looking into it for me. I don't want to take any meds right now because I'm trying to keep my body clean for some future babies that haven't been conceived yet. I took Lexapro for a short period of time last year and it was terrific. I don't have nonstop anxiety anyway... it comes and goes due to everyday life stressors. I am not against meds in the least, but I do think that getting my anxiety under control is within reach for me. It doesn't stop me from doing anything, but it doesn't feel good, either.

So anyway, she's looking into neurofeedback, even though it primarily seems to be used for ADHD/ADD. I'm not clear on the difference between neurofeedback and biofeedback, aside from the facts I've read on the internet about peripheral vs central nervous system, and that neurofeedback is easier and more permanent.

I bought some biofeedback software a few months ago, called Journey to Wild Divine. You put sensors on your fingers and it monitors your body temp and heartbeat. Sounded good in theory. However, I found the format to be really frustrating because you have to play a computer game to "find" objects on which to practice the biofeedback. I just want to cut to the chase (gee, do you think I'm impatient? good candidate for learning how to relax, mebbe?). It's like going on an easter egg hunt on 5 acres and realizing that there are only 2 eggs to be found on the entire property. I spent 45 minutes on it last night and never found any of the dang objects. I was more frustrated after 45 minutes than I was to begin with.

Yoga does help me a lot, but it takes me a very long time before my mind will relax - usually not until the very end of the class. And two hours later, I'm as wired as I was to start out with. I'm trying different methods and instructors because I do feel confident that yoga is a good long-term solution for me, but I'm not quite there yet.

Anyway, back to neurofeedback... has anyone tried it? Opinions?
