I am just aware of it. I make the choice not to let it get out of control. If I am out of balance, I go back to the center and do some introspection. Its only when I am really happy that I go out of control. Then I have to catch myself before I become someone that I am not. When I am sad or depressed, I don't want anything to take me out of that(as far as substances go) because I know inside somewhere is a window of insight.
