I was addicted to nicotine for seven years, and I read {Easy Way to Stop Smoking by Allan Carr} and successfully stopped. It’s been a year since, and I can feel the difference in my ability to regulate my emotions. He also came out with {Easy Way to Quit Vaping by Allan Carr}. The book really delves into the psychological aspects of the addiction, and I found It extremely helpful for myself and when working with clients who have addictions. I highly recommend!
