After spending close to a year dealing with sudden ED (it started suddenly), I tried Between Us. To date, I believe that my condition is improving. I appreciate that Between Us provides programmatic process, with repeated exercises that build on each other with the hope of a solution. I think that Between Us is something anyone with the problem should try - but I would emphasize that you may need to transform your experience to a more mindful approach. In my case, I started meditating and therapy to deal with work-related stress and clinical depression. These factors likely caused my ED issues. After trying different programs, I started working with Balance's Foundations program to deal with my stress and depression. I was working through the program when I began Between Us as well. Balance is a more general meditation program that teaches the basics of mindfulness and seems to provide an excellent companion to Between Us, which deals with this more specific goal.
