Days are not all that important to me personally.
Tweaking our plan as you have discovered is critical, although I remain sober I have rough days from time to time as well, I reflect on those feelings or emotions and let them go, I will often tweak my plan along the way as well.
I find it helpful to keep a list in my wallet of what it was like in the event I am not being mindful the list also has everything I have gained back by being sober and I know I would loose all that if I were to slip and what I have gained back including my health is all that matters to me.
