"Stop thinking Start living" by Richard Carlson

I've read this book once a while back now and I enjoyed it and thought the ideas this author suggests and brings to the table were remarkable.

Unfortunately I gave up after only a day due to being in the most stressful day to day situations I had ever been in. I was overwhelmed and decided that I surely couldn't keep this technique going, I had no time to read and understand the ideas more clearly, so I went back into my anxious state pretty quickly after falling asleep feeling amazing due to the book. Now though, things are more relaxed and I'm able to begin a new technique per say. I'm thinking of reading this book again and wondering if anyone has read it or know about it's method suggested in the book to be effective with overcoming OCD/Pure O and other mental health problems. If so, how effective was it?

Thank you, hope to hear from you guys.
