There is no such thing as a geographical cure. You can't move to Hawaii to get sober. Saying that you are getting a fresh start by leaving town does not keep you away from the first drink or drug or other form of acting out. Similarly, if you are sober, just because you are moving to a new place does not mean that you are going to have to go back to your old using self. Your sober self goes with you too. And you will stay sober so long as you find new recovery meetings at the new place you are going.
Don't change places thinking that moving will keep you sober. YOU NEED TO CHANGE YOURSELF TO STAY SOBER. Also, if you are moving and you are sober just get to meetings and keep recovery your priority and you will do fine.
