Day 4: So far, so good. Yesterday I experienced something a bit odd - I was fine until around 9 in the evening, then i went out to get some food (against my dietary rules) almost automatically. I realized that I was acting on autopilot and stopped myself, then came back home and immediately almost relapsed. I closed the window in time nevertheless, but it seems like the cause of this was due to a depletion of willpower. I'm going to try and rest periodically during the day just to make sure this doesn't recur.
