I have researched all of these, and I can't make up my mind about which one to choose. It could help me, or make me miserable. But I don't have to! What I can say for sure is that this is the best stress relief product available. It works, it works! How long can you go without it? It's a great time to use this product. It has helped my life tremendously. I have been using this product for nearly a month. My husband and I went camping for about a month this summer, and there was an incredible sense of well being, which I could not have experienced in the days since the car accident. It's the difference between being at home all day, and at home all the time. In fact, I have just used this product after I finished reading "I Feel Lucky." I was amazed at how much I got away from my past life . I was even able to put the book down and go back to the real world. The effects seem to last longer when I was on the beach. There is not one product that can really do what this is doing, but I want to share this story with anyone who might be considering one of the many books on the list.
