This product has been excellent for the patients I see in practice, many of whom go on to buy units themselves. I also use it as well – it helps manage anxiety and find it good for sleep maintenance (I have no problems with sleep initiation). It is also great in that it is SAFE. I have had no adverse effects or bad reactions at all, both for me and for patients. Some have better results than others, but it is clearly something to seriously consider when contemplating treatment options.
