After 1-2 cups daily for 10 years I quit drinking coffee at the beginning of 2022 to see what impact it would have

The main benefit I’ve observed is that my energy levels throughout the day are more level, whereas before they followed a sine wave. Low upon waking up, high following my morning coffee, then dipping towards the end of the day.

No noticeable impact on sleep quality or other aspects of my life that I’m aware of, but I don’t plan to go back to drinking coffee now that I’m off of it.
