The 10th day is not inherently ant more dangerous than the 1st, 2nd, 5th, or 25th. I used to think that certain milestones were "new territory", and more dangerous. They are not. Why should the same trigger be harder or easier on different days? Yes, some days we are more tired, more 'out of it', or not in such a great mood for whatever reason. That however, is not inherent in any specific day. I could nust as easily have a hard time on the 5th day as on the 25th day. There is no day that is inherently harder than another. (Although sometimes a trigger can be harder to overcome than other triggers.) Once I was able to convince myself that the main thing is avoiding triggers (i.e. filtering my devices), and self control, the actual number of clean days made less of a difference.
Sometimes, the yetzer pulled a sneaky move on me. He'd say, you just reached X number of clean days, that is a record. He would say that I deserve some time off, where I could let my guard down, where I can indulge a bit, etc. Sometimes his trick would work, sometimes I was able to strengthen myself to avoid this pitfall!
Whatever works for you!
When I started the 90 day chart, I wasn't really sure that I could make it. I did it, and more. So can you!!!!!!
