I have had experience with it. I don't think it does anything despite all of these "studies". My boyfriend thinks it help him though. It's really hard for me to talk and concentrate enough to watch that stupid light go back and forth and actually, I think it distracts me.

I have no experience with it. I found this information: "Eye movement desensitization and reprocessing (EMDR) is a form of psychotherapy that was developed to resolve symptoms resulting from disturbing and unresolved life experiences. It uses a structured approach to address past, present, and future aspects of disturbing memories. The approach was developed by Francine Shapiro to resolve the development of trauma-related disorders as resulting from exposure to a traumatic or distressing event, such as rape. Clinical trials have been conducted to assess EMDR's efficacy in the treatment of post-traumatic stress disorder (PTSD). In some studies it has been shown to be equivalent to cognitive behavioral therapy and exposure therapies, and more effective than some alternative treatments (see effectiveness sections below). However, the effectiveness of the mechanisms behind EMDR have been questioned, with most leading researchers concluding that cognitive restructuring (which is common in most therapies for PTSD), rather than the eye movements, are responsible for change. Although some clinicians may use EMDR for various problems, its research support is primarily for disorders stemming from distressing life experiences."
