I see why fasting is a part of so many religions. I cannot deny a certain "spiritual" feeling on my fasting day. I want to try to again to explore this interesting feeling. It was a "subjective, internal experience" as Sam Harris might call it. Once the intense cravings faded the fasting felt like a meditation.

And when the cravings were bad I just told myself: "You can eat _____ tomorrow. Tomorrow is not far away."
