What bimini said
Take the resoucefulness and discipline you have for other things like running and music,
and apply it to this situation.
You can do it, but the absolute will to do it must be in place for it to work.
What is your sobriety plan? What actions do you plan for if tempted?
What extra support are you giving yourself, body and soul, while you do this?
That was the key to success for me. . .
