I have found the Letting Go Paraliminal to be very effective. Last summer when it first came out I ordered a copy and it helped me move through a very intense bout of anxiety that nothing else did. Since then I use it fairly regularly, I even listen to the sleep track a number of times in a row to deepen my process. Sometimes it takes a few times of listening that way to get through a pattern of thinking, or a collection of thought patterns that are closely linked. It has been very liberating for me.
