Well in my book you're to be commended for having the patience and determination to continue holosync for as long as you have....I don't think I would have continued with holosync for more than a couple of months if I hadn't been noticing any benefits from it.

Just one question Stevie: what do you actually experience while you're listening to the tracks? Do you just feel bored, do you fall asleep, or do you do some kind of specific meditative technique, etc.
Also you've tested your headphones for proper stereo separation right?
