Sitting here at about the 27 hour mark, having a nice relaxing cup of black decaf coffee before bedtime. Easy one so far. I had a busy day at work that started early, and ran late, so that kept me occupied. I also got in most of my planned exercises and even about a 45 minute walk in lieu of eating during my lunch break.
I will see in the morning how long I want to go. 7am Saturday gets me to 36 hours, which is my typical weekly target, but I often end up going 42 or so, just because I am not always that hungry first thing in the morning.
