I think counting days is a personal choice as well... different things work for different people. I tend to keep a general idea of where I am, but I don't count days. Right when I got sober I did count and I would be thinking, "Wow! I feel great! I can actually do this!!" and then I would look at the calendar and see I was only on day 2 or 3. It felt like sooo much longer. It would discourage me. So now I just go with it and keep on keepin on.
Best of luck!!
