For less than the cost of one therapy session, you can have a great self-help tool if you are unable to get help from a specialist. Or, if you are working with a therapist, it provides many tools to assist you while you are working on your own. So far, patients are telling me that it is great. I was able to go almost 20 minutes without today. I don't know what it is, but once I stop using the app, the ticking starts up almost immediately.
