I've been doing a weekly 30 minute session with neuro optimal since september. I can't really say I've noticed anything other than that it is generally relaxing to be in a little room sitting on a comfortable chair while listening to tchaikovsky or rainforest sounds. I have no obligations in that time other than sitting quietly. Maybe there has been a subtle effect, but I think I'm pretty good with assessing how my brain reacts to things, and I kind of expected noticeable shift by now. Has anyone else worked with this technology? I'm particularly interested the view of someone who had worked with it for 6 plus month, a year, etc.
