Those first few days, I felt really, really good. My brain felt more awake, and I had tons of energy right away, which lasted for the entire workout. I felt strong and especially psyched to work out. My CrossFit buddy even noticed and said I was even more chatty than usual, which says a lot since the class is at 5:45 a.m.! Yoga felt good, and so did my home BBG workout.
I will say that throughout the week, I felt more hungry than usual. I continued with my normal eating window of noon until 7 p.m., but I was starting to feel hungry around 9:30/10 a.m., when normally I don't feel hungry until noon. I drank a lot of water on those mornings, as well as tea, but didn't have anymore coffee.
