During Lent, I abstained from all coffee (and caffeine). The first two weeks were a bit rough, but I got through the fog and am fine now. I got used to drinking this hibiscus tea, which is caffeine-free. It’s delicious and sour.
After Lent, I went back to having some coffee, but not daily. I don’t want the same groggy effects if I ever miss coffee or the awful flu-like symptoms of low-energy and achiness. I do enjoy the taste of coffee, but it is something I’m probably going to use sparingly in the near future, or drink decaf.
