Oh also?  I pulled out my old Big Book out of curiosity about my last sobriety date.  It was August 19th, and if I remember correctly I later found out that the sobriety date should be your first day sober, not the last time you drank.  I don't know why I didn't get that but whatever, I think I may have had the day wrong.  So my last sobriety date was August 20, 2010.  The last time I drank was on Friday, so I guess my new sobriety date is August 20, 2011.  I am not sure if I will count days, maybe at first, but seriously how weird is that?
