how you count days is really up to you and your own knowledge of what is honest and true. what's really important is that you stopped yourself instead of being foolish and saying "well one sip means I screwed up, I might as well drink it all and get some more."
For me, early sobriety requires a lot of planning in terms of avoiding people, places, and things that will trigger you. Keeping these at a great distance recognizes my own flawed humanity and my openness to temptation and conditioned responces. You have learned something here, and not blown it whole hog. Take what you have learned, and move forward~~~~
glad you posted Yoga~~~~!
