First off, congratulations on not only doing it but sticking with it. It is a constant mental battle to stay off the weed. I enjoyed smoking, if I could I'd be smoking right now. Quit in '96 following a heart attack. My cardiologist at the time looked at me in my hospital bed and said the immortal words that changed my life:

"If you continue to smoke, you are going to die."

And the rest is history.
