Yesterday, I was at two events where food was free, but I avoided taking any. This was a little awkward. I missed being able to snack during the day. But what affected me most was that the tea bags that I am using to make my tea do not give me as strong tea as I usually get from the coffee shop. I suffered some symptoms of caffeine withdrawal. I woke up this morning with a headache that I attribute to the caffeine withdrawal. The headache went away later, and today this seems to have gone better than yesterday, either because I timed my tea better, or because the body has become used to the lack of caffeine.
I had some interesting conversations with my kids where they calculated the price of their breakfast and compared it to the price of my breakfast. My son thought that he was "winning" because his breakfast was more expensive than mine.
