I did not read much of either of your guys' posts.
That being said I own the program, and I meditate often.
Meditation is extremely powerful. Much more so than 95% of nootropics.
The program can help you increase you meditation/concentration skill for newbies, but like anything else, meditation is a practice that takes time to get good at. That being said, spending your time meditating in any fashion is what counts. It doesn't really matter if it with a fancy program or not. Though th emwave is niffty(i got caught up into the marketing bullshit, like we all do), if you can create the habit of meditating for 20 min in the morning and night, that will improve anxiety once you have the meditation muscle built up. At first it will suck and feel like you are getting nothing out of those 20 minutes(probably much like working out is for people just starting out.) But over time that skill increases (its very subtle).
With that skill set you will always have a handle on your anxiety and emotional nature to an extent.
I heard the emwave in 6 months can get you up to the level of a daily meditation practitioner of 2 years. (I heard this from someone who was a meditation advocate and uses the emwave with clients. She strictly worked with drug addicts(the most anxious, neurotic, insecure folks there is when they don't have their drugs.)
essentially, if you are not rich, save your money. Buy a book or two on meditation and start the practice. Emwave won't matter shit if you don't practice meditation.
