I have my level one Reiki. When I first heard about it I was very skeptical. A friend insisted on giving me Reiki one day when the sinus medication I was taking just wasn't working. One session and I was hooked. I did some research and found out it worked great on animals too. My dog Mistletoe was very ill and not expected to live much longer. I took the first level class. It was amazing what it did for Mistletoe. It extended her life (with quality) for more than 6 months. The vet was so impressed that he too studied Reiki. It works wonderful on my ADD nephew. What power to put him to sleep when he is bouncing off the walls! And, when my niece broke her back, I could help with pain management. I reiki my boyfriend while flying as he is petrified to fly. I can usually have him so relaxed before take off that he barely notices it anymore. Still not sure how it works. It is just one of those unexplainable things that I will never question again. I know for me personally, it has helped with stress and a chronic sinus problem. If you get the chance, I recommended looking into it.
