Exercise played a critical role in my early recovery. Honestly, in many ways it saved my life and health as much as anything else I did.
But it is a double-edged sword....I have to admit that I did take it too far, and became dependent on it for a time. Was this as bad as being addicted to alcohol? No, but it took some work later on for me to release my need to work out 2-3 hours a day! On the good side, though, working past the exercise thing did help me learn balance.
