actually you don't need a sponsor to START working the steps. feel free to jump in any time! if you're old skool, get a fresh notebook and a GOOD pen and get busy writing. IMHO steps involve a lot of writing. if you prefer the computer thing, fire up a fresh word doc type the first step at the top and then get busy on the keyboard, tell YOUR story of how you got HERE. try not to glamorize or embellish, just stick to the facts.
be well and good luck! sobriety is quite the adventure!
