If you are a recovering METH addict, what keeps you clean and sober?

I AM 18 YRS OLD, AND I HAVE BEEN USING METH SCINCE I WAS NEARLY 15 YEARS OLD. I HAVE BEEN TO REHAB 3 TIMES, BUT NOTHING SEEMS TO WORK. I COULD REALLY USE SOME ENCOURAGEMENT FROM PEOPLE WHO KNOW WHAT I AM GOING THROUGH.

ONLY SERIOUS COMMENTS PLEASE
