Almost exactly five years ago, I had to come to terms with my pot addiction. Between hard work, intense and personal therapy with an awesome psychologist for more than two years, I came to terms with so many things. My life, my relationship with my wife... wouldn't be where it is today without it. For me - again, for me - the best thing that happened for me is: 1) a specific event that triggered a cascading series events and 2) my intense desire to help myself. I can't stress enough how much the right psychologist helped me.
That said, good luck, CG.
